Question

If the point G(–4, 6) was moved horizontally 4 units to the left, which of the following is the correct mapping to define the translation? (x, y) Right-arrow (x, y + 4) (x, y) Right-arrow(x + 4, y) (x, y) Right-arrow (x, y – 4) (x, y) Right-arrow (x – 4, y)

Answer 1

(x, y) Right-arrow (x – 4, y)

Explanation:

just did it

Answer 2

(x, y ) → (x - 4, y )

Explanation:

A horizontal move of 4 to the left means subtract 4 from the x- coordinate, leaving the y- coordinate unchanged, thus

(x, y ) → (x - 4, y ) ← translation rule
