Answer
You're correct.
Step-by-step explanation
When a given point with coordinates A (x, y) is reflected over the y-axis, the y-coordinate remains the same and the x-coordinate takes up a negative in front of it. That is, A (x, y) changes after being reflected across the y-axis in this way
A (x, y) = A' (-x, y)
So, for each of these,
A (-3, 3) = A' (3, 3)
B (-3, -2) = B' (3, -2)
C (0, 0) = C' (0, 0)
Hope this Helps!!!
