You move down 4 units and right 10 units. You end at (5, -5). Where did you start?

Question

i dont know how to do this and i really need help because im confused on this

Answer 1

Assume you started at (x,y). The wording of the problem translates into

y - 4 = -5 (moved down 4 units)

x + 10 = 5 (moved 10 units to the right)

Now just solve the 2 equations for x and y.
