What is the general equation for x2 + (y - 7)2 = 49 ?
How does your book define the "general equation" for this sort of conic? How is the above not the "general form"?

When you reply, please include a clear listing of your efforts so far, so we can see where you're getting bogged down. Thank you! ;)
