y=-2x+8
---------------
It's a straight line, so 2 points are sufficient.
Pick numbers for x and find y.
x = 0, y = 8 --> (0,8)
x = -4,y = 0 --> (-4,0)
Plot the points and draw a line thru them.
I don't know another way.
Well, actually I do, but this one works.

If we build a table for x and y values, your answer will become very apparent and you'll know how to graph it. So let's do that first.

Notice that when x=0, y=12 ... and when x=4, y=0.
With these two points, you can draw a straight line in the cartesian plane.
All other results help us confirm we're on track.
So we graph like shown below:
