Make table of 3 solutions graph each solution 3x+y=1

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
