Transformation Coordinate Rules

What happens to the x- and y-coordinates of a point, if it is reflected over the x-axis?

• The x-coordinate stays the same and the y-coordinate changes the sign.

• The x-coordinate changes the sign and the y-coordinate stays the same.

• The x-coordinate and the y-coordinate stay the same.
