I have no clue on how to answer it and A is (2,2) B is (5,-1) and C is (1,-2)

Answer:
A: (-2,2)
B: (-5,-1)
C:(-1,-2)
(4,1) reflected across the axis is (-4,1)
Step-by-step explanation:
To reflect across the y axis you keep the y value the same but do the inverse of the x value
(and the opposite for reflecting across the x axis)
For example (2,2) reflected across the y axis will become (-2,2) and just do this for all of them.
I hope this helps :)
