Question

Right triangle LMN has vertices L(7, –3), M(7, –8), and
N(10, –8). The triangle is translated on the coordinate plane so the coordinates of L’ are (–1, 8).

Which rule was used to translate the image?

(x, y) → (x + 6, y – 5)
(x, y) → (x – 6, y + 5)
(x, y) → (x + 8, y – 11)
(x, y) → (x – 8, y + 11)

Answer 1

Compute the translation vector from L to L': (-1 - 7, 8 - (-3)) = (-8, 11).
So the rule is (x, y) → (x − 8, y + 11).
