Question

△ABC is reflected to form​​ ​ △A′B′C′ ​. The vertices of △ABC are A(3, 1) , B(1, 5) , and C(6, 9) . The vertices of △A′B′C′ are A′(−1, −3) , B′(−5, −1) , and C′(−9, −6) . Which reflection results in the transformation of ​ △ABC ​​ to ​ △A′B′C′ ​​?

Answer 1

that would be a reflection across the y axis resulting in a -x

Explanation:

Answer 2

The reflection of the triangle across y = -x is the new triangle.
