You move up 3 units and down 7 units. You end at (2, - 4). Where did you start?

Answer: (2,0)

Step-by-step explanation: being that you are only moving up and down, only the y value is being moved, so the x value will stay the same. If y starts at - 4, need to solve for - 4 = y + 3 - 7.

Y = 0

(2, 0)

Step-by-step explanation:

0+3=3

3-7 = - 4

you only said up and down, so that would be on the y-axis, so the x - coordinate would remain the same
