Answer:

The center is (0,-5) and the radius is 9

Step-by-step explanation:

The equation of a circle can be given by

(x-h)^2 + (y-k) ^2 = r^2

where (h,k) is the center and r is the radius

(x-0)^2 + (y- -5) ^2 = 9^2

The center is (0,-5) and the radius is 9

#1.
Here what you do is cross multiply.
$\frac{8x}{13x}$
#2.
Same as #1, just cross multiply.
$\frac{9x}{12}$

You get the gist?
