Step 1 : Recall what is the x-intercept

The x-intercept is the point on the graph were y= 0. So find the x-intercept by substituting y = 0 in 4x -3y = 12.

Solve for x

4x = 12

x = 3

Step 2 : Recall how to plot a set of coordinates on the graph.

Move 3 spaces to the right of x-axis

Plot (3,0).This is the x-intercept.

Step 3 : Recall what is the y-intercept

The y-intercept is the point on the graph were x = 0. Find the y-intercept by substituting x = 0 in 4x -3y = 12

-3y = 12

y = -4

Step 4 : Plot (0,-4) on the graph. This is the y-intercept.

Step 5 : Join these points to get the straight line 4x - 3y = 12
