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
