(A) Find the parametric equations for the line through the point P = (3, 4, 4) that is perpendicular to the plane 4x−4y+2z=1.

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.

x = 

y =  
z = 

(B) At what point Q does this line intersect the yz-plane?

Q = (      ,        ,        )
