On a coordinate plane, how are the locations of the points (3, -1) and (-3, 1) related?
A. locations unrelated
B. reflection across the x-axis
C. reflection across both axes*
D. reflection across the y-axis
Thank you all.

To determine how the locations of the points (3, -1) and (-3, 1) are related on a coordinate plane, you can visually analyze their positions.
First, let's plot these points on a coordinate plane. The point (3, -1) has a positive x-coordinate and a negative y-coordinate, so it lies in the fourth quadrant. The point (-3, 1) has a negative x-coordinate and a positive y-coordinate, so it lies in the second quadrant.
By looking at their positions, we can see that the y-coordinates of both points have the opposite sign, while the x-coordinates have the same sign. This indicates that the points are reflections across the y-axis.
Therefore, the correct answer is D. reflection across the y-axis.
Even though it is not stated,
It could also be a reflection in the origin.
You are correct : )
Two transformations have been performed on the ordered pairs. One right after the other.
