Parametric equation.. life application tricky...

I am having some difficulty understanding this question i would appreciate all the help i can get solving it.

a track on a hill side leading to a house, is in the shape of a smooth curve given parametrically by

a copy of the hillside is placed in the x-y plane so that a post (P) on the northern end of the track is located at the point where t=2. the hill also follows the equation find

1) the slope of the track at point (P) where the post is located.

2) the equation that can be used to represent the straigh line from the point P to the origin on the x-y plane

3)An expression for the steepness of the hill..

i have though about this but not sure what angle to take this from.. i would really appreciate any help i can get.
