Answer:
A. (x,y)-(-x,y)
Step-by-step explanation:
1. Look at the first FG, It is Positive X and Positive Y
2. A reflection is simply flipping something to the opposite side, So now look at which part the 2nd FG is.
3. Now as we notice the G is in the Negative X, So that would be -X, But then when we look at the Y, It is in the positives!
