    (x+7) ^2 + (y+4) ^2 = 6^2

    or

    (x+7) ^2 + (y+4) ^2 = 36

    Step-by-step explanation:

    We can write the equation of a circle in the form

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

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

    (x--7) ^2 + (y--4) ^2 = 6^2

    (x+7) ^2 + (y+4) ^2 = 6^2

    or

    (x+7) ^2 + (y+4) ^2 = 36
