Question

you start at (1, -4). 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.
The original point is (1, - 4). Moving right means adding to the x - coordinate.

Step2: Calculate new x - coordinate

The original x - coordinate is 1. We move 3 units right. So the new x - coordinate is \(1 + 3=4\). The y - coordinate stays as - 4.

Answer:

(4, - 4)
