__Problem I:__

*(The coeffiecients throw me off, I don't know what I'm supposed to do with them)*

**9x^2 + 16y^2 = 144**

Determine:

a) coodinates of the centre

b) lengths of the major and minor axes

__Problem II:__

Sketch a graph of the ellipse

4x^2 + (y+1)^2 = 9

PS: For future posts would it be of any help to include the textbook refered to etc?

In this case:

Mathpower 12: WE

Problem I - p. 150 #9

Problem II - p. 150 #19

PPS: I've also italicized any comments about my attemts - since people seem to like to help out people making an attempt.
