## 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
