Question

you move right 6 units and up 1 unit. you end at (4, -1). where did you start?

Explanation:

Step1: Reverse horizontal movement

Moving right 6 units is addition in x - coordinate. Reverse is subtraction. So for x - coordinate of starting point, $4−6=-2$.

Step2: Reverse vertical movement

Moving up 1 unit is addition in y - coordinate. Reverse is subtraction. So for y - coordinate of starting point, $-1 - 1=-2$.

Answer:

$(-2,-2)$
