Question

you start at (-5, -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 starting point is $(-5,-4)$. Moving right 3 units means adding 3 to the x - coordinate.

Step2: Calculate the new x - coordinate

The original x - coordinate is $- 5$. Add 3 to it: $-5 + 3=-2$. The y - coordinate stays as $-4$.

Answer:

$(-2,-4)$
