You reflect triangle PQR, with coordinates P(-4, -4), Q(-1, -3), and R(-3, -1), across the x-axis, across the y-axis, and across

notka56 [123]

Answer:

P'( 4, -4)

Step-by-step explanation:

The double reflection across the x-axis does nothing, so the net effect is a single reflection across the y-axis. That effect is to negate the x-coordinate:

reflection across y-axis: (x, y) ⇒ (-x, y)

Then P(-4, -4) ⇒ P'(4, -4)
