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 coordinates of the reflection point C' and then use those coordinates to find the coordinates of point C.
If the reflection point C' is (2, -2), this means that C is the point that lies on the same horizontal line but is the same vertical distance from the x-axis as C', just in the opposite direction.
Since the reflection across the x-axis will reverse the sign of the y-coordinate, the y-coordinate of point C is the negative of the y-coordinate of C'.
Therefore, the coordinates of point C are (2, 2).
