    After analyzing an image of a road I have successfully obtained a quadratic equation which describes the behaviour of the line.

    Now I want to map that line into a 2d image. I have been looking at http://en.wikipedia.org/wiki/3D_projection (Perspective projection section) but it only explains the method for a point rather than a line. Is there any way how I can map the line equation instead?

    Compute a lot of points on the equation and project each of them.
