Sorry if I'm late to this question but here's a short answer for those who are in a hurry or being timed :) Hope this helps!

Answer 2

Answer: (x, y) = (-x, -y)

Step-by-step explanation:

To solve this, you can match the coordinates of points on the triangles and choose the correct answer from there.

The highest point on the triangle, S, has coordinates of (3, 5).

The reflected triangle's point S has coordinates of (-3, -5).

Point Q on the triangle has coordinates of (1, 0)

Point Q on the reflected triangle has coordinates of (-1, 0).

Matching these two points and their reflections to the answers, the only answer that fulfills both points correctly is (x, y) = (-x, -y).
