Question

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

Explanation:

Step1: Calculate new x - coordinate

Moving left 1 unit means subtracting 1 from the x - coordinate. The initial x - coordinate is 3. So, $3 - 1=2$.

Step2: Calculate new y - coordinate

Moving down 2 units means subtracting 2 from the y - coordinate. The initial y - coordinate is - 1. So, $-1-2=-3$.

Answer:

$(2, - 3)$
