graph C, then graph M.  find the slope pattern from C to M and then continue the pattern one more point.

same as before

for x                                       for y

 -1 = ( -5 +x)/2            2 = (-2 + y)/2

-2 = -5 + x                    4 = -2 + y

solve for x and y

add 5 to both sides           add 2 to both sides

x = 3                                     y = 6

ordered pair is (3, 6)
