Which glide reflection describes the mapping ABC Def

Answer:
B
Step-by-step explanation:
Point B is above AC. Corresponding point E is below the corresponding segment DF. This means the reflection is vertical, across a horizontal line.
In order to get the figure to its final position, it must be translated to the right by 6 units. This translation matches choice B.
(x, y) ⇒ (x +6, y -1), and reflected across y = 0
