The points (9, 5) and (-9, 5) have the same y-coordinate (5) but different x-coordinates (9 and -9). This indicates that they are reflections of each other across the y-axis.
Therefore, the correct answer is:
C. reflection across the y-axis.
On a coordinate plane, how are the locations of the points (9 , 5) and (-9 , 5) related?
A.
locations unrelated
B.
reflection across both axes
C.
reflection across the y-axis
D.
reflection across the x-axis
