You can put this solution on YOUR website!
All you need is to find 2 points on graph paper and draw a line.
The points are made of 2 numbers the 1st for x and the 2nd for y that looks like this (x,y).
For example, what does y equal when x=0? y=-4 so (0,-4) is one of our dots.
What does y equal when x=4? y=0 so (4,0) is one of our dots.
What does y equal when x=8? y=4 so (8,4) is one of our dots.
Line up the dots with your ruler and the graph will look like this.
