Question

you start at (2, -2). you move up 4 units. where do you end?

Explanation:

Step1: Recall coordinate - movement rule

In a coordinate - plane, moving up changes the y - coordinate. The x - coordinate remains the same when moving vertically.
The starting point is $(2,-2)$, where the x - coordinate $x = 2$ and the y - coordinate $y=-2$.

Step2: Calculate the new y - coordinate

When moving up 4 units, we add 4 to the y - coordinate. The new y - coordinate is $y=-2 + 4=2$. The x - coordinate stays $x = 2$.

Answer:

$(2,2)$
