Question

Please check my answer....




The vertices of a triangle are P(3, 7), Q(7, –6), and R(–8, 7). Name the vertices of the image reflected across the x-axis. (1 point)
P'(3, –7), Q'(7, 6), R'(–8, –7)
P'(–3, 7), Q'(–7, –6), R'(8, 7)
P'(–3, –7), Q'(–7, 6), R'(8, –7) <----
P'(3, 7), Q'(7, –6), R'(–8, 7)

Answer 1

You're thinking of reflecting across the y axis...

when you reflect across the x axis it changes the sign of the y coordinate
