Question

you start at (4, -1). you move right 1 unit. where do you end?

Explanation:

Step1: Recall coordinate - movement rule

Moving right in a coordinate - plane changes the x - coordinate. The rule for moving right is to add to the x - coordinate while keeping the y - coordinate the same.
The starting point is $(4,-1)$.

Step2: Calculate the new x - coordinate

The original x - coordinate is 4. We move 1 unit right, so we add 1 to the x - coordinate: $4 + 1=5$. The y - coordinate remains $-1$.

Answer:

$(5,-1)$
