(2,7)
(6,12)
(10,17)

Some moderator deleted my response for some reason. I did it mentally.. but I guess I'll show proof.

1) (2,7)

   -4y = -5x - 18
-4(7) = -5(2) - 18
   -28 = -10 -18
   -28 = -28

2) (6,12)
 
        -4y=-5x-18
  -4(12) = -5(6) - 18
       -48 = -30 - 18
       -48 = -48

3) (10,17)

         4y=-5x-18
  -4(17) = -5(10) - 18
       -68 = -50 - 18
       -68 = -68

See the pattern? 2,6,10 and 7,12,17?
