Question

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

Explanation:

Step1: Recall coordinate - movement rule

Moving right on a coordinate - plane changes the x - coordinate. The y - coordinate remains the same when moving horizontally.

Step2: Calculate the new x - coordinate

The initial x - coordinate is 1. Moving 3 units right means adding 3 to the x - coordinate: $1 + 3=4$. The y - coordinate is initially - 1 and remains - 1.

Answer:

$(4,-1)$
