# Math Help - Coordinates of Points

1. ## Coordinates of Points

What are the coordinates of point (2,–3) after it is reflected over the
x-axis?

(1) (2,3) (3) (–2,–3)

(2) (–2,3) (4) (–3,2)

Reflection over the x-axis means:
- The x-coordinate doesn't change
- The y-coordinate changes its sign.

Therefore the answer is (1): P'(2, 3)
