Answer:

Explanation:

The center is going to be written as (x + 2) and (y + 8).

Notice that the point x and y values are turned around. That happens because you want to determine where the circle's center is when it is put in the circle formula

The radius must be squared. It represents a distance.

(x + 2)^2 + (y + 8)^2 = 4^2

The formula is the one above. The graph shows the center at (-2,-8)
