Question

you move up 9 units and left 3 units. you end at (-1, 4). where did you start?

Explanation:

Step1: Reverse the horizontal movement

Moving left 3 units is reversed by moving right 3 units. If the final x - coordinate is - 1, then the starting x - coordinate is $-1 + 3=2$.

Step2: Reverse the vertical movement

Moving up 9 units is reversed by moving down 9 units. If the final y - coordinate is 4, then the starting y - coordinate is $4-9=-5$.

Answer:

$(2, - 5)$
