Equation of a Circle:

$\sf (x - h)^2 + (y - k)^2 = r^2$

igreen · Answer

Where $\sf (h, k)$ is the center.

igreen · Answer

So in this case:

$\sf h = -7$
$\sf k = -3$
$\sf r = 2$

igreen · Answer

Can you plug those numbers in? @Omgthatgirl

omgthatgirl · Answer

yes

igreen · Answer

Okay, tell me what you get.

omgthatgirl · Answer

Ok is this how the equation should be  (x-7)^2 + (y-3)^2=2^2
