Question

you move up 1 unit and down 1 unit. you end at (2, 4). where did you start?

Explanation:

Step1: Analyze vertical movement

Moving up 1 and down 1 unit cancels out (since \(1 - 1 = 0\) vertical change).

Step2: Determine starting x - coordinate

The x - coordinate doesn't change (no horizontal movement mentioned), so starting x is 2.

Step3: Determine starting y - coordinate

Since vertical movement cancels, starting y is same as ending y, which is 4.

Answer:

\((2, 4)\)
