Question

If point D' is the image of D(-2,1) under a reflection across the x-axis. What are the coordinates of D'?

Answer 1

Answer:

(-2, -1)

Step-by-step explanation:

When reflecting across the x-axis, the x coordinate remains the same, but the y-coordinate turns to its opposite. So to get D from D', keep -2, and make 1 a -1.

Answer 2

The answer is (-2,-1)
