Question 1 • ! MCHS (CR25) - GEOMETRY

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

Answer
A
(x, y) → (x + 6, y – 5)
B
(x, y) → (x – 6, y + 5)
C
(x, y) → (x + 8, y – 11)
D
(x, y) → (x – 8, y + 11)

Explanation

To find the translation, compare L(7, −3) with L′(−1, 8). The x-coordinate changes by −1 − 7 = −8, and the y-coordinate changes by 8 − (−3) = 11. So every point moves left 8 units and up 11 units, which is the rule (x, y) → (x − 8, y + 11), choice D.
