\bf \textit{equation of a circle}\\\\ 
(x- h)^2+(y- k)^2= r^2
\qquad 
center~~(\stackrel{}{ h},\stackrel{}{ k})\qquad \qquad 
radius=\stackrel{}{ r}\\\\
-------------------------------\\\\
x^2+(y+9)^2=25\implies [x-\stackrel{h}{0}]^2+[y-\stackrel{k}{(-9)}]^2=\stackrel{r}{5^2}\qquad \qquad \quad \stackrel{center}{(0,-9)}
