Question

Can someone help me!!?

The vertices of a triangle are P(4,7), Q(8,-1), and R(-9,6). What are the vertices of the image reflected across axis?

Answer 1

Reflecting points across the x-axis is simply changing the sign on the y-value by multiplying it by -1.
P(4, -7) Q(8, 1) R( -9, -6)
I hope this helps
