Question

you move right 1 unit and up 8 units. you end at (5, 3). where did you start?

Explanation:

Step1: Reverse x - coordinate movement

Moving right 1 unit to reach 5. So the starting x - coordinate is $5 - 1$.
$5-1 = 4$

Step2: Reverse y - coordinate movement

Moving up 8 units to reach 3. So the starting y - coordinate is $3 - 8$.
$3-8=-5$

Answer:

$(4, - 5)$
