# How do you graph (x - 3)^ 2 + (y + 1) ^2 = 9 ?

Draw a circle with $\left(3 , - 1\right)$ as center and $3$ as radius.

#### Explanation:

Standard equation of a circle with $\left(a , b\right)$ as center and $r$ as radius is

${\left(x - a\right)}^{2} + {\left(y - b\right)}^{2} = {r}^{2}$.

Hence, in the above, $\left(3 , - 1\right)$ is the center and $3$ is the radius.

Hence to draw the graph, just draw a circle with $\left(3 , - 1\right)$ as center and $3$ as radius.
