Question

you start at (2, 0). you move down 5 units. where do you end?

Explanation:

Step1: Recall coordinate - movement rule

Moving down in a coordinate - plane changes the y - coordinate. The x - coordinate remains the same when moving vertically.
The starting point is $(2,0)$. When moving down 5 units, we subtract 5 from the y - coordinate.

Step2: Calculate the new y - coordinate

The original y - coordinate is 0. After moving down 5 units, the new y - coordinate is $0 - 5=-5$. The x - coordinate stays as 2.

Answer:

$(2, - 5)$
