Online Help in graphing linear equations

Posted on November 16, 2011. Filed under: Uncategorized | Tags: , , |

Previously we have discussed about learn calculus and In today’s session we are going to discuss about Linear Equation, It is one of the essential topic of 7th standard mathematics, so today we are going to understand the basic concepts behind Linear Equations. Before going in deep with Linear Equations we need to understand the concept of intercepts. Intercepts are where a graph crosses either the x-axis or the y-axis or we can say that Intercept is a point which intersects on a curve in XY axis of a graph. An x- intercept is where the graph crosses the x-axis (that is where the value of y = 0) whereas a y-intercept is where the graph crosses the y-axis (that is where the value of x = 0).

general form of x-intercept = ( x, 0)

general form of y-intercept = ( 0, y)

Now the first question is that how intercepts plays an important role in defining Linear equations? Let’s see about linear equations. In simple mathematical manner we can say that any equation that when graphed produces a straight line then the equation is called as Linear Equation. The general form of a linear equation in two variables like x and y is…..

y = mx + b

where x and y are two variables and m and b are two constants. The constant m determines the slope or gradient of that line and the constant b shows the point at which line crosses the Y-axis. Constant b is also known as Y-Intercept.

Intercepts also play an important role in graphing linear equations. A linear equation graph always forms a straight line. We can take Online help in graphing linear equations. Various Online graphing calculators are available over internet which provides you the exact graph along with the steps to graph the Linear equation. Let’s take an example : Graph Y = 1/5x + 10

The steps to follow in solving above linear equation: Firstly locate the y-intercept on the graph and then plot the point on the graph. At this point use the slope of line to plot another point, and at last draw the line which connects these two points.

Online help and linear equations

Posted on November 14, 2011. Filed under: Uncategorized |

Previously we have discussed about free math solver  and Today we are going to talk about Linear equations , A Linear equation is an algebric equation in which each term is either a constant or product of constant and a variable. Linear equation is an essential phenomenon of mathematics to solve many non- Linear equations by converting them into linear one .

Let us take an example ..

6x + 4 = 22

in the above expression ‘x’ is a variable with an integer coofficient .

So now in the first step, shift ‘4’ to Right Hand Side (RHS) of equation and subtract it, because when a element shift from Left Hand Side (LHS) To RHS. Then the sign is changed.

6x = 22 – 4

6x = 18

now move ‘6’ into denominator of RHS.

X= 18 / 6

x= 3

thats it is the way to get the integer value which replaces the variable in any linear equation.

General form of Linear equation .

y= mx + b

here ‘y’ and ‘x’ are variables , and M is slope of the equation. every Linear eqauation represents a Linear shape in 2D plane , like this one forming a straight line in which ‘M’ is a constant representing slope of the line and another constant ‘b’ refers to the point at which line crosse the ‘y’ axis.

A Linear Equation Graph is gives the pictorial representation of the straight line on the plan surface. The area of this line should be limited in a fixed region which is according to the value of right side of an enquality equation. For graphing a a linear equation we need x-intercept, y intercept and slope.

Slope of the line = (change in y points)/ (change in x points)

M = ∆y / ∆x

Linear Equations and Linear Equation Graph

Posted on November 14, 2011. Filed under: Uncategorized | Tags: , , |

In every science subject, the problems which are already existing in their standard form are said to be a Linear form problem. These problems are easier to solve because there is no requirement to apply something else on them rather than just direct implementation of the standard formulas. Similarly, in mathematics, linear equations are resolved by use of standard principles and formulas. But the reason behind the given importance to linear equations is their big involvement in solving non- linear complex queries. The complex math queries are generally normalized or decomposed in such a manner that its derivatives or factors become linear form. To learn the ways or conversion of complex non-linear problems into linear forms, students can take the math online help tutoring websites which is the most favorable way in present time.

Grasp concepts of Linear Inequalities

Posted on November 8, 2011. Filed under: Uncategorized | Tags: , , |

Hey! Friends, today we are going to discuss about linear inequalities problems and their graphing procedure. Students can learn with the help of an online math tutoring website “Tutorvista” which covers all the topics of linear inequalities. Linear inequality is a form of representing linear equation with some certain boundary or we can say when the area of any straight line is restricted by some numerical value in the graph than this condition is said to be of linear inequality. Linear inequality is represent by using inequality symbols such as greater than, less than in the linear equations rather than equal to sign. The solution process of any linear inequality query is almost as same as linear equations but, one point which has to be remember while solving questions related to linear inequalities is that while multiplying linear equations with ‘–ive’ sign we have to flip the inequality symbol with its opposite sign as:

-( y + 2 < 2) = ( -y – 2 > -2)

 Graphing of a linear inequality problems gives its pictorial representation which gives result as straight line on the plane surface. The area of this line should be restricted or limited in a fixed region which is according to the value of right side of the inequality equation. The basic terms used for graphing several equations are: x intercept, y intercept and slope. While using slope formula if we have endpoints of the line as (x1, y1) and (x2, y2) then use of this formula includes a condition that is x1 ≠ x2so that we get finite answer.  

Slope of the line M = (change in Y points) / (change in X points)

                            = ( y2 – y1 ) / ( x2 – x1).

Importance of Linear Equation in Math

Posted on November 5, 2011. Filed under: Uncategorized | Tags: , , |

Mathematical expression is represented in the form of any polynomial equation which may or may not consist of various derivatives of different order. But linear equation is a form of polynomial which consists of all the derivatives of same order, because of this property of linear equations, their solution is easy in comparison to other polynomials. That's why the complex equations of math are converted in linear form to solve them with ease. For non- linear to linear conversion there are various standard principles of math used. The standard form of a linear equation is

Ax + By = C

Here A, B and C are integer constants and x and y are variables of same order.

 

There is a basic concept while solving linear equations that if an equation consists of 'n' different variables than 'n' linear equation of those variables is required in a system to solve that linear equation system by replacing the variables with their numerical values.

 

When we try to do the 2D representation of any linear equation then this process is said to be Graphing, and every time graphing of a linear equation forms a straight line on a plane surface. The pictorial representation of a linear equation graph is plotted with respect to Cartesian axes co-ordinates which are calculated by x and y intercepts. In mathematics, graphing is done according to various graphing functions which are distinct for various forms of equation in maths.

 

If you want to learn more about linear equations and the procedure of solving and graphing them then TutorVista, an online math tutoring website, provides online help for students for round the clock.

 

This online help is provided by intelligent and professionally certified online math tutors so you can rely on them without hesitation.

Solve Equations using Online Help

Posted on November 4, 2011. Filed under: Uncategorized | Tags: , , |

In algebra we have got a lot of different types of equations like linear equation, quadratic equation, and polynomial equation. In mathematics, an equation is a statement which has two expressions separated by = sign having same value or in other words we can say it shows the balance situation where the value of one side is exactly same as the opposite side. While we go through these all different equations. We got a lot of problems and we need guidance to solve them. On internet, Online Help is available to solve our problems related to all different types of equations.

Today we will discuss about linear equations. A linear equation is an algebraic equation where all the terms can be a constant or product of a constant and a single variable. It can have multiple variables also.

For example :-

7h + c = 18

4h + c = 9

To find out the solution either we can add or subtract both equations. For given example we will use elimination method. So it will be

(7h – 4h ) + (c – c ) = 18 – 9,

3h = 9,

h = 9 / 3,

h = 3

Now we have the value of variable h = 3 and we can find out the value of c by using this value in any of equation

Let’s find out the value of c

7h + c = 18,

7*3 + c = 18,

21 + c = 18,

c = 18 -21,

c = -3

Now we have got the value for both variables and we can use these values in any of given equation to cross check the answer.

A Linear Equation Graph is 2d representation of an equation in respect of its coordinates.

Graphing Equations through TutorVista

Posted on November 1, 2011. Filed under: Uncategorized | Tags: , , |

In mathematics, every problem can be solved only when it will be in any form of mathematical equation. Mathematical equations are of various types like quadratic equation, differential equation, transcendental equation and many more forms. But one thing is common in all these forms is that they all are further categorized as linear equation and non – linear equation. But sometimes math problems are not directly given in form of any mathematical expression, they are provided in word form with proper information and we have to convert that information in the form of linear equation.

As we said earlier that math equation is in two forms linear and non linear. In math, all the standard principles are only applicable when equation is in linear form. That’s why to solve any non linear equation it is first converted into its relative linear form.

Let us talk about graphing of linear equation. Graphing is the way of representation of any linear equation in form of straight line on a 2D plane with respect to its co-ordinates of both X and Y Cartesian axis. For doing graphing of any linear equation, two terms endpoints or intersection points on the X, Y axis and slope of the line are required. For finding slope of the line we use slope formula and for determining endpoints of the line x and y intercepts are calculated.

The general form of any linear equation whose graphical representation is to be done is as follows:

y = mx + b

This linear equation will represent a straight line with’ m’ slope in respect of x axis.

For knowing more about linear equations and its graphing procedure, students can prefer to an online math tutoring website named as TutorVista, which provides you online help for various math queries.
