Question

I tried doing the steps but I'm stuck. Can I get help on this pls?

Answer 1

Don't know if this helps but...

Explanation:

When rotated 270 `=>`A(-1,3) B(-6,6) and C(-1,6)
Then when it's reflected in the y axis
A(1,3) B(6,6) and C(1,6)

This is the single transformation of reflection in the line y=x

Hope it helps.
