Hey. I have a math quiz tomorrow, and am working on a worksheet with 20 problems. I'm not sure I understand these problems, so if possible can someone please possibily solve these samples? I was absent, and am totally loss.

1. Find standard form for parabola:

Foci(4,-1) directrix: y= 3

2. Elipses:

(x+4)^2/ 9 + (y-3)^2/ 36= 1.

Find vertices, foci, length of major and minor axis.

3. Hyperbolas:

4x^2 - 6y^2 - 24y+ 8x - 12= 0

State center, vericies, and foci.

Basically, each of these 3 types are the kinds I'll be expected to know how to solve on the quiz tomorrow. I need samples done, so I can understand the processes. At the moment I'm clueless as to how to solve them. Any and all help will be appreciated!
