Answer:
Since you know your class better than I do, if your answer can be given in coordinate-form (x,y), here's what I would do.
To very easily count the distance between coordinates, which I learned when I was in Geometry, was to simply count the difference between your two coordinates.
-2 + 6 = 4
-4 + 7 = 3
The distance is...
(6,7)
