Answer: C (-2, 2), (1, -1), (3, 1). (2,4)
It will help to rotate the image so the x-axis is horizintal and the y-axis is vertical.
Step-by-step explanation:
Imagine the prefigure twirling on a parallel bar like a gymnast.
When it's up-side down the point that was at (1,1) flips to (1. -1) and the point that was at (3 -1) flips to (3, 1)
As you chech your choices, that knocks out most of the other possibilities.
But you should still verify the other cocorinates.
Hint: if the reflection is across the x-axis, the x values will be the same in the pre-image and the reflection, the y- values will change accorfing to their distance from the x-axis.
