Question

The vertices of a triangle are P(–7, –4), Q(–7, –8), and R(3, –3). Name the vertices of the image reflected across the line y = x.

P'(4, 7), Q'(8, 7), R'(3, –3)
P'(4, –7), Q'(8, –7), R'(3, 3)
P'(–4, –7), Q'(–8, –7), R'(–3, 3)
P'(–4, 7), Q'(–8, 7), R'(–3, –3)

Answer 1

When you reflect a point in the line \(y=x\), all you do is swap the \(x\) and \(y\) co-ordinates around.
Are you able to complete this for yourself now?

Answer 2

So the answer would be C right

Answer 3

Yep :)
