Question

you start at (2, 1). you move up 8 units. where do you end?

Explanation:

Step1: Recall coordinate movement rule

When moving up in a coordinate plane, the x - coordinate remains the same, and the y - coordinate increases by the number of units moved. The starting point is \((2,1)\), so the x - coordinate is \(2\) and will stay \(2\).

Step2: Calculate the new y - coordinate

The initial y - coordinate is \(1\), and we move up \(8\) units. So we add \(8\) to the initial y - coordinate: \(1 + 8=9\).

Answer:

\((2,9)\)
