Some Hyperbola, ellipse, parabola help.

I have 13 questions out of a larger group that I need some direction with.

If anyone wants to answer them, go for it, if not get me started please. I did fine with my others, these I can only think of bits or pieces I may need.

Thanks ahead of time.

1. Determine the perpendicular distance between the parallel lines y=2x+3 and y=2x-5.

2. Find the sum of the x and y intercepts of the line x/4 + y/8=2.

3. Find the focal width of the parabola **y=2(x)**squared.

4. Find the focus of the parabola **y**squared**-6y-4x=17=0**.

5. Which of the conic sections have the property that the ratio of the distance from a point P on the curve to a fixed point F to the distance from P to a fixed line is a positive constant less than 1?

6. A line is drawn tangent to the ellipse **x**squared + **3**ysquared **= 84** at the point (3,5). Determine the area in the first quadrant below the tangent line.

7. Find the foci of the hyperbola **x**squared**/17** **- y**squared**/8 = 1**.

8. Determine the eccentricity of the hyperbola **2y**sqrd**-3x**sqrd**=1**.

9. Determine the asymptotes of the hyperbola **x**sqrd**-y**sqrd**/4=1**.

10. Find an equation for the hyperbola with vertices (0,+/- 3) and foci (0,+/- 5).

11. Find the vertices of the hyperbola **9y**sqrd**-18y-4x**sqrd**-16x-43=0**.

12. Find the equations for the directrices of the hyperbola **x**sqrd**/16-y**sqrd**/9=1**.

13. Find an equation for the ellipse with vertices (+/- 3,0) and directrices x=+/-4.
