Question

The point (2, -3), is the top of a triangle. Which point would it map to if the triangle was translated up 7 units and reflected about the y-axis.
(-2, 4)

(-2, 10)

(2, -4)

(-1, 3)

Answer 1

Answer: (-2,4)

Step-by-step explanation:

When you go up any number of units, you add it to the y-coordinate. So -3 + 7 = 4. That would make it, (2,4). The next step would be reflecting it across the y-axis. And whenever you reflect across the y-axis, the x-coordinate always changes.
