    Yes, it's a circle. Hint: The standard form of a circle is \((x-h)^2 + (y-k)^2 = r^2\). Group like terms together and complete the square.

    you probably want to list the center and radius though

    aweosme! :) thanks :) so the center would be (3,5) and the radius would be about 3.6 ?

    or just sqrt(13) works
