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′?

Answer 1

Explanation:

If you reflect about the y-axis, only the x-coordinates reverse sign while the y-coordinates stay the same....

P'(2,-4), Q'(3,-1), R'(4,-4)
