Andrea has to find a third point, C , to form a triangle on the coordinate plane shown. She is told the coordinates of its reflection point, C′ , across the x -axis are (2,−2) . What are the coordinates of point C

To find the coordinates of point C, we need to find the reflection point C' across the x-axis.

Since the reflection point C' is (2, -2), this means that the y-coordinate of point C' is the negative of the y-coordinate of point C.

Therefore, the y-coordinate of point C is -(-2), which is 2.

Since C' is the reflection of C across the x-axis, the x-coordinate of point C remains the same.

Therefore, the coordinates of point C are (2, 2).
