    parametric equations

    (A) Find the parametric equations for the line through the point P = (-5, -4, 1) that is perpendicular to the plane
    Use "t" as your variable, t = 0 should correspond to P, and the velocity vector of the line should be the same as the standard normal vector of the plane.
    (B) At what point Q does this line intersect the yz-plane?



    how do I start this?

    The line has direction -3i + 2j - k (same as the normal to the given plane) and passes through the point (-5, -4, 1) ....
