Hello!
The equation for a circle is
[tex](x - h)^{2} + (y - k)^{2} = r^{2} [/tex]
(h, k) is the center
You find what numbers make the equation
Since x is not subtracted from anything h = 0
Since k is positive k is the negative of that number
The equation is [tex] (x - 0)^{2} + (y - -9)^{2} = 25[/tex]
The center is (0, -9)
Hope this helps!
