Answer:

(-5,-2)

Explanation:

the equation involved is a circle let us clearly write the equation first:

From the standard equation of the circle:

So from the equation given above, our x would be -5, and our y is equivalent to -2.

So the center of our circle is located at the point (-5,-2)

Since, the equation involved is a circle let us clearly write the equation first:

(x+5)^2+(y+2)^2=21^2

From the standard equation of the circle:

(x-h)^2+(y-k)^2=r^2

(h,k)=(x,y)

So from the equation given above, our x would be -5, and our y is equivalent to -2.
So the center of our circle is located at the point (-5,-2)
