Question

you move up 3 units. you end at (-1, -2). where did you start?

Explanation:

Step1: Identify coordinate change rule

Moving up affects only the $y$-coordinate; $x$-coordinate stays the same.

Step2: Set up start coordinate equation

Let start point be $(x,y)$. Moving up 3 units gives $y + 3 = -2$.

Step3: Solve for start $y$-coordinate

$y = -2 - 3 = -5$

Step4: Confirm start $x$-coordinate

$x = -1$ (no horizontal movement)

Answer:

$(-1, -5)$
