Hi. I'm in a panic, because i have this take home quiz i need to do for class, and I'm pretty lost when it comes to algebra II.

The homework says that I need to scetch the ellipse whose foci are (1,4) and (1,2)

and whose minor axis is 8 units, then i have to write the equation of that ellipse.

also i need to, from standard form, classify each conic, the identify its center:

1. (x+6)^2 ---(y-5)^2

________ + _________= 1

------- 81 - - - - - 64

2. x^2+8y^2-4x-16y-4=0

3. x^2+y^2+6x+6y=0

And of course, I forgot my textbook in my locker, and I've searched all over the web, but am still having trouble understanding this stuff. Someone please help me.
