Question

You move down 3 units and up 3 units. You end at (-3, 4). Where did you start?

Answer 1

Explanation:

All motion here is up and down, so the x-coordinate does not change.

Work backwards to answer this question:

(-3, 4), and down three units, and then up three, puts you where you started, at (-3, 4).

Answer 2

Answer: You started at (-3, 4)

Explanation:

If you started at (-3, 4) and moved down 3 units, you would be at (-6, 4). If you moved back up 3 units, you would be at your original starting point (-3, 4).
