#### Answer:

#### Explanation:

The standard equation of a circle is

So, we're given

Moreover, we're given

So, plugging the given information into the standard equation yields

To plot the circle, first, begin at your center,

Then, since the radius is

This will result in the center,

```
graph{(x+2)^2+y^2=25 [-10, 10, -5, 5]}
