Answer:
(D) (-1, -3) and (1, -3) are reflections of each other over the y-axis.
Step-by-step explanation:
(-1, -3) is in Quadrant III (-, -) and (1, -3) is in Quadrant IV (+, -). The points are reflected over the y-axis. It cannot be over the x-axis because the signs for (1, -3) would change.
This is best demonstrated if you have a visual and graph to plot your two points. You can see that the line of reflection is in a vertical direction, and vertical means it is y-axis related. Try plotting the points on a graph.
