Math Blog on Graphing Linear Equations with One Variable

Posted on February 14, 2012. Filed under: Uncategorized | Tags: , , |

Previously we have discussed about differential calculus and In today’s session we are going to discuss about Graphing Linear Equations with One Variable, Graph designing is interesting and easier part of the discrete mathematics. In the discrete mathematics we study about the diagrammatic representation of the graph. Graph is an illustrative representation of points, which are directly or indirectly interconnected to each other. In the graphical representation we are analyzing the various paths, calculation and size of the program.  Points are shown by vertices of the graph and interconnecting lines shown by edges of the graph. Through this blog we are going to discuss about Graphing Linear Equations with One Variable.

Linear Equations are the equations, which are collection of variable and numbers. In linear equation we find out the value of the variable which satisfies the given equation.

To create graph of linear equation we have to follow some steps:

1) Select the value of x and find the value of y.

2) Prepare the table of values of x and y

3) Then plot those values on graph by taking appropriate scale.

4) After plotting the points arrange them by a creating straight line.

Example: Draw the graph y = 2x

Solution: Here we take the Linear Equations with One Variable, where values of y depend on the values of x.

Value of x 1 1.5 2 2.5
Value of y 2 3 4 5

When we put the value of x in the given equation then we obtain the value y, which is given in the table. Now we put these values in the graph. In the below given graph we show you how to plot the equations value in the graph.

                                       

This is the graph of y = 2x. Similarly we can draw graphs of other linear equations.

In the next session we will discuss about Graphing Linear Equations  and You can visit our website for getting information about algebraic expression and 10th question paper.
