AABC is reflected across x = 1 and y = -3. What are the coordinates of the reflection image of B
after both reflections?
(-7, -1)
(7,1)
(7,-1)
(-7, 1)

Answer 1

(7,1)

Explanation:

B: (-5, -7)

After reflection in x = 1

B': (-5+6+6, -7)

B': (7, -7)

After reflection in y = -3:

B": (7, -7+4+4)

B":(7, 1)

Answer 2

(7,1)

Explanation:

When you reflect it across x = 1, you get (7, -7). When you reflect that across y = -3, you get (7,1).
