Question

you start at (3, -1). you move left 2 units and right 1 unit. where do you end?

Explanation:

Step1: Identify starting x-coordinate

Start at $x=3$

Step2: Move left 2 units (subtract 2)

$3 - 2 = 1$

Step3: Move right 1 unit (add 1)

$1 + 1 = 2$

Step4: Keep y-coordinate unchanged

$y=-1$ (no vertical movement)

Answer:

$(2, -1)$
