Conics Type And Orientation

[camino]

Homework Statement

There are 2 problems a and b.
I've solved for both already.
I just need to know how to describe them by type and orientation.
In other words, what does what I got tell me in regards to type and orientation and how do I know this for future problems? (e.g. hyperbola or ellipse oriented vertically or horizontally)

a) (x-3)^2 (y-1)^2
-------- - -------- = 1
9 1

b) (x+1)^2 (y-1)^2
-------- + -------- = 1
25 4
