Question

The point D(-3, 1) is reflected over the x-axis. What are the coordinates of the resulting point, D′?

Answer 1

The rule for reflecting over the X axis is to negate the value of the y-coordinate of each point, but leave the x-value the same.

Explanation:

For example, when point P with coordinates (5,4) is reflecting across the X axis and mapped onto point P', the coordinates of P' are (5,-4).
