    (x + 4) ^2 + (y-2) ^2 = 16

    Step-by-step explanation:

    We can write the equation for a circle with the formula

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

    Where (h, k) is the center and r is the radius

    We know the center is at (-4,2) and the radius is 4

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

    (x + 4) ^2 + (y-2) ^2 = 16
