Question

You reflect triangle PQR, with vertices P(-2, -4), Q(-3, -1), and R(-4, -4), across the y-axis to get triangle P′Q′R′. What are the coordinates of triangle P′Q′R′?
A.
P′(-2, 4), Q′(-3, 1), R′(-4, 4)
B.
P′(2, -4), Q′(3, -1), R′(4, 4)
C.
P′(-2, 4), Q′(-3, 1), R′(4, -4)
D.
P′(2, -4), Q′(3, -1), R′(4, -4)

Answer 1

Answer:

D. (2, -4),(3, -1), (4, -4)

Step-by-step explanation:

Hello!

When you reflect over the y-axis you reverse the x.

Negatives become positives and positives become negatives

(-2, -4) turns into (2, -4)

(-3, -1) turns into (3, -1)

(-4, -4) turns into (4, -4)

look for the answer that has (2, -4),(3, -1), and (4, -4)

The answer is D

Hope this helps!
