    Answer:

    option a

    Step-by-step explanation:

    we know  the equation of a circle is:

    (x-x1)^2 +(y-y2)^2= r^2

    center= (x1,y2)

    radius =r

    in this case we have:

    center= (5,-2)

    r=3

    so we have:

    (x-5)^2 +(y-(-2))^2=9

    finally we have:

    (x-5)^2 +(y+2)^2=9
