1. ## Planes and Lines!

I can't find a way of getting a line equation from the point!

Regards,

Regards,
The equation through P and perpendicular to the plane is: $\displaystyle <1,0,-2>+t<1,1,-2>$.

3. Therefore the line intersects with the plane at:

(1 + t) + t -2(-2 -2t) = -3

.: t = -4/3

.: The exact point of intersection is:

(-4/3, -4/3, -8/3)

What next?
