    we know that

    To generate the equation of the parabola, we start with this equation

    (x - h) ² = 4p * (y - k)

    where "h" and "k" are the (x, y) values of the vertex.

    "p" is the difference between the focus "y-value" and the vertex y-value.

    p = (6-5) = 1

    Now we put these numbers into the equation:

    (x - h) ² = 4p * (y - k)

    (x + 2) ² = 4 * 1 * (y - 5)

    (x + 2) ² = 4 * (y - 5)

    the answer is

    (x + 2) ² = 4 * (y - 5)
