Use the image to answer the question.
A coordinate plane shows the x and y axes ranging from negative 6 to 6 in increments of 1. A line joins two plotted points, upper A and upper B. The coordinates of the plotted points are as follows: upper A is left parenthesis 5 comma 1 right parenthesis and upper B is left parenthesis 3.5 comma 3.5 right parenthesis.
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 ?

Since the reflection point of C across the x-axis is (2,-2), this means that the y-coordinate of C is the negative of the y-coordinate of C', and the x-coordinate of C is the same as the x-coordinate of C'.
So the coordinates of point C are (2, 2).
