Solve for x or y and plug it back in to the respective variable.

anonymous · Answer

so first, you're going to put all the x on one side, and all the y on the other.
Let's add 6x and 3y to both sides, which will gives you:
y= 5x + 38 = 9    Now, subtract 9 from both sides, which gives you:
y= 5x + 29
From that equation above, plug the points (x,y) in and see if the coordinates matches.
1  = 5(-6) + 29   WRONG!
6  = 5(-1) + 29   WRONG!
-6 = 5(9) + 29    WRONG!
-1 = 5(-6) + 29  CORRECT!
