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

Answer:
(3, 4)
Step-by-step 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)
