Hey! Lets solve this shall we ?
So, we must find the image coordinates from point ABC after translating and reflecting across the line y = 1.
Now, A(3,3) turns into A'(3,4), B(9,3) turns into B'(9,4) and C(6,7) turns into C'(6,8) after making the translation. Now we must turn these points into a final point after reflecting about the line y = 1. We subtract 1 from each y-value of each point then compute 1 minus the y-value of the translation point such that
A'(3,4) => A"(3,-2)
B'(9,4) => B"(9,-2)
C'(6,8) => C"(6,-6)
I hope this helped!
