Homework Help: Math

Posted by Joshua on Friday, October 17, 2008 at 6:41am.

Hi guys,
In the question "It is given that P (0, 3), Q(7, 5), R(9, -2) and S are vertices of a square. A circle A passes through the points P, Q, R and S. Find the equation of this circle. Hence or otherwise find the equation of circle B which is the image of A under the reflection about y axis."

Can someone help me with the part hence or otherwise? I've found that the equation of the circle is x^2 + y^2 -9x -y -6 =0

Thanks =)
