Question

Point Q' is the image of Q(3, -4) under a reflection across the x-axis.

What are the coordinates of Q'?

Answer 1

(3, 4)

Explanation:

In a reflection across the x-axis, the point moves to the other side of the x-axis. The y-coordinate becomes the opposite, and the x-coordinate remains the same.

Q(3, -4) -----> Q'(3, 4)
