How are the ordered pairs (4, 9) and (4,−9) similar, and how are they different? Are the two points related by a reflection over an axis in the coordinate plane? If so, indicate which axis is the line of symmetry between the points. If they are not related by a reflection over an axis in the coordinate plane, explain how you know.
Given the point (−5, 2), write the coordinates of a point that is related by a reflection over the x- or y- axis. Specify which axis is the line of symmetry.
