You move down 1 unit and up 3 units. You end at (-3, 5). Where did you start?

Answer 1

You move down 1 unit and up 3 units. You end at (-3, 5). Where did you start?

Note that you did NOT move left or right.

You started at (-3,3). "Down 1 unit" took you to ((-3,2) and "up 3 units" took you to (-3,5).

Answer 2

Let (x,y) be your original position:

(x - 1, y + 3) = (-3,5)

x-1 = -3 ---> x = -2

y + 3 = 5 ---> y = 2

(x,y) = (-2,2)
