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

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

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