Question

Choose the algebraic description that maps ΔABC onto ΔA′B′C′ in the given figure. Question 9 options:

A) (x, y) → (x, y – 6)
B) (x, y) → (x – 6, y)
C) (x, y) → (x, y + 6)
D) (x, y) → (x + 6, y)

Answer 1

B) (x, y) → (x – 6, y)

Explanation:

Each x-value in the image is 6 less than in the pre-image. Each y-value is the same. That means x gets mapped to x-6, and y gets mapped to y:

(x, y) → (x – 6, y)
