Circle 1 is centered at (−5, 4) and has a radius of 15 units. Circle 2 is centered at (−5, −3) and has a radius of 9 units.

What transformations can be applied to Circle 1 to prove that the circles are similar?

I believe the transformation rule is (x, y-7), but I don't know what the scale factor is.
