△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′ ?

reflection across the x-axis

reflection across the y-axis

reflection across y = x

reflection across y=−x
