Here's the questions. This is in the form of a "chart" on my worksheet, and consists of writing equations in 3 forms:
1) Slope intercept
2)Point-slope
and 3) Standard for ( AX+BY=C ) First person to answer ALL questions gets a best answer in the 4 hour time slot, guaranteed.

1) [ 2x - 5y = 8 ] Find points on the line, along with the slope and y intercept. Write slope intercept form and point slope form based on the only given info, the standard form.

2) Points are (-3, 2), slope is 0. Find y intercept, and find the slope-intercept form, point slope form, and standard from, based on given info.

3) Points are (-4,-7), slope is undefined. Find exact info,( y intercept form, etc) JUST LIKE PROBLEM 2 ABOVE.

Please help, I PROMISE a best answer for the most accurate answer!^ ^

Heres the question-

The volume of a cylinder is 600(pi, sorry, cant use the pie symbol on this computer) cm^3, its height is 18 cm. What is the approximate radius of the cylinder?

And heres another one thats very similar-

The volume and height of a cone is the same as the cylinder, what is its radius?

Thanks.

At age 13/14, I had many "OBE's". Then it stopped. I think maybe because I switched rooms with my mom. (In the old room, LOADS of weirdness went on, including what I suspect to be an encounter with an incubus, as well as other beings and generally unexplained activity - Might have had something to do with an electromgnetic field?). I can remember as a young girl, being very frustrated that I could never get through the ceiling when I would have an OBE. I even drew a little keyhole on the ceiling, hoping that would help (which it didn't!). When I reached the ceiling, it seemed very dense, not solid, dense. I would try to push through, and then abrubtly be sucked back into my body. And forget going through walls, I always floated upward, with such force that I really had little control. Anyways, lo' and behold it happened again today, twice (I am now 27). The tingly sensation took over, and up I flew...until I got to the ceiling. Same dense feeling. Same being sucked back. Any ideas why?

O.k. so I have to find the vertex point ....

Here is what I have figured out so far

The point on the graph ( creates a U shape ) are

(0,0) - (1,2) - ( 2,8) and so on

would this equation match it ----- Y = 2x^2 ????


Also how do I go about finding the vertex point??? Thanks
