(A) Find the parametric equations for the line through the point P = (-5, -4, 1) that is perpendicular to the plane http://mathcs.chapman.edu/webwork2_f...5c2e08db31.png

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?
