Question

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

Explanation:

Step1: Calculate new x - coordinate

The starting x - coordinate is 1. Moving right 1 unit, we add 1 to the x - coordinate. So, $x=1 + 1=2$.

Step2: Calculate new y - coordinate

The starting y - coordinate is - 1. Moving down 3 units means subtracting 3 from the y - coordinate. So, $y=-1-3=-4$.

Answer:

(2, - 4)
