    (h+8) ^2 + (y + 1) ^2 = 9

    Step-by-step explanation:

    The equation of a circle can be written as

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

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

    (h - - 8) ^2 + (y - - 1) ^2 = 3^2

    (h+8) ^2 + (y + 1) ^2 = 3^2

    (h+8) ^2 + (y + 1) ^2 = 9

    (x + 8) ² + (y + 1) ² = 9

    Step-by-step explanation:

    Equation of a circle

    (x - h) ² + (y - k) ² = r²

    (x - - 8) ² + (y - - 1) ² = 3²

    (x + 8) ² + (y + 1) ² = 9
