I've asked this 4 times with no help so help me find the equation of a parabola with the vertex at the origin with the focus on the y axis. There is a line with slope 1/2 going through the focus. Find the value of the focus (or length of P if you prefer) and then find the equation. Explain please and help me on this or I will die trying to figure this out.

This question doesn't make sense to me. The focus can be anywhere inside the parabola. Every point on the coordinate system can have a line with slope 1/2 going through it, so that doesn't help at all.
Also, I don't know what you mean by "length of P".

If you have a parabola of the type
y=a*x^2 (vertex at the origin)
the focal length is 1/(4a)
a line going thru the focus will be the following
y =mx +b
y =(1/2)x +1/(4a)
I think there might be something missing from your question. Is a point that the parabola and the line cross known?

try using an interval estimate to p,give slope a degree value ,
