Answer:
Circle centered at (0,−4) with a radius of 3.
It has equation form as: x^2 + (y + 4)^2 = 3^2.
Answer: since the center is (0,-4) and have a radius of 3 then the standard form of an equation of a circle will be (x-0)^2+(y-(-4))^2=9 or 3^2. the formula of the standard form is (x-h)^2+(y-k)^2=r^2 where the center is (h,k).
The general form will be x^2+y^2+8y+7=0
