Find the glide reflection rule to map ABC onto A'B'C'in the given figure.
A) Translation: (x, y) → (x, y + 7); Reflection across the x-axis
B) Translation: (x, y) → (x + 7, y); Reflection across the x-axis
C) Translation: (x, y) → (x + 7, y); Reflection across the y-axis
D) Translation: (x, y) → (x-7, y); Reflection across the x-axis
