i don't know why i am not getting this material like i should, anyway,, i am stuck here..

A Plane P is orthogonal(perpendicular) to the line L: x=4+2t, y=-1+3t, z=2+t and passes through the point A =(4, 1,7) Find the point where the plane P intersets the x-axis.

(Hint: Find the equation of the plane P)

Answer: ( , , )

also tell me how can i better understand parallel, orthogonal and skew stuff on line and plane
