What is the equation of the graph below?

Step-by-step explanation:

The given graph is a circle which is centered at (-2,-4) and of radius 2.

The standard form of a circle is given by

Here (h,k) is the center and r is the radius.

Hence, we have

h = -2, k = -4 , r = 2

Therefore, equation of the circle is

7/2

(decimal: 3.5)
