Question

you move left 4 units and up 5 units. you end at (-5, 4). where did you start?

Explanation:

Step1: Reverse x - coordinate movement

Moving left 4 units means subtracting 4 from the x - coordinate. To find the starting x - coordinate, we add 4 to the ending x - coordinate. The ending x - coordinate is - 5. So, $x=-5 + 4=-1$.

Step2: Reverse y - coordinate movement

Moving up 5 units means adding 5 to the y - coordinate. To find the starting y - coordinate, we subtract 5 from the ending y - coordinate. The ending y - coordinate is 4. So, $y=4 - 5=-1$.

Answer:

$(-1,-1)$
