So on graph it would be a line. You just need to select any three points on a line.
Easiest way is to just start with x = 0 then solve for y and then you would have one solution.
Do x=1 then x=2.
Once you do that, you should get solution (0, 1), (1, -2), and (2, -5)
So table would looks like this:
x | 0 1 2
y | 1 -2 -5
