    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)
