Introduction to plot line graph:

The coordinate graph is called as a Cartesian plane. The graph contains a few vertical lines called coordinate axes. The vertical y axis value and the horizontal axis value is the x axis value. The points of intersection of those 2 axes values are called the origin of coordinate graphing pictures. To a right point of the origin on the x axis value and above the origin on the y axis represents positive real numbers. To the left point of the origin value on the x axis or below the origin on the y axis represent negative real numbers. In this article we shall discuss about plot a line graph.

For line plot example:

Example 1:
Solving the given linear technique equation and plot the line graph.
2x - y – 8 = 0 ----- (1)
Solution:
In the first step we reduce the equation (1) in the form of y = mx + c, we get the following term
2x – y - 8 = 0
2x – y = 8
2x = y + 8
Multiply -1 for equation (1), we get
- 2x = - y - 8
y = 2x – 8
We plot the table for above equation,there we get Incredible Online Math
