Answer:

[tex](x+8)^{2} +(y+3)^{2}=4[/tex]

Step-by-step explanation:

we know that

The equation of the circle in center radius form is equal to

[tex](x-h)^{2} +(y-k)^{2}=r^{2}[/tex]

where

(h,k) is the center of the circle

r is the radius

In this problem we have

[tex](h,k)=(-8,-3)[/tex]

[tex]r=2\ units[/tex]

substitute

[tex](x+8)^{2} +(y+3)^{2}=2^{2}[/tex]

[tex](x+8)^{2} +(y+3)^{2}=4[/tex]
