WILL MARK BRAINILIST AND 20 POINTS!! Triangle PQR is transformed to triangle P'Q'R. Triangle PQR has vertices P (3, -6), Q (0, -9), and R (-3, 0). Triangle P'Q'R has vertices P'(1,-2), Q' (0, 3), and R' (-1, 0).
Write the coordinates of triangle P’’Q”R” obtained after P’Q’R’ is reflected about the y-axis.
