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

(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

(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
