Question

A line segment has endpoints (1, 1)
and (4, 4)
. Demonstrating the properties of reflections across the y
-axis, what are the reflected endpoints?(1 point)
Responses

(−1, 1) and (−4, 4)

(−1, −1) and (−4, −4)

(−1, 1) and (4, 4)

(1, −1) and (4, −4)

Answer 1

Reflection across the y-axis changes (x, y) to (−x, y). So (1, 1) → (−1, 1) and (4, 4) → (−4, 4).

Answer: (−1, 1) and (−4, 4).
