A reflection over the x-axis changes which part of the coordinates?

Explanation:
Reflecting over the x-axis flips points vertically. This keeps the horizontal position the same, but the vertical position is inverted. So a point (x, y) becomes (x, -y). That means the sign that changes is the y-coordinate, while the x-coordinate stays unchanged. For example, (3, 4) becomes (3, -4).
