Reflections on the Coordinate Plane

A reflection is a transformation that flips a figure over a line, creating a mirror image.

The x-axis is the horizontal line in a coordinate plane where the y-coordinate is zero.

The y-axis is the vertical line in a coordinate plane where the x-coordinate is zero.

To reflect a point (x, y) over the x-axis, change the sign of the y-coordinate to get (x, -y).

To reflect a point (x, y) over the y-axis, change the sign of the x-coordinate to get (-x, y).

The result is (3, -4).

The result is (5, 2).

A' is (-2, 3).

B' is (7, -8).

The x-coordinate remains the same, and the y-coordinate changes sign.
