Y = - x+2

x-3y = - 18

How do I solve these to graph the solutions?

Plug in y from the first equation into the second to solve for x

X - 3 (-x + 2) = 18

Distribute

x + 3x - 6 = 18

4x - 6 = 18

4x = 24

x = 8

Plug x in the top equation to find y

y = - (8) + 2

y = - 6

Your two answers are

X = 8

Y = - 6
