Can someone help with this multi-part question. i did the first three but it doesnt seem right!(adsbygoogle = window.adsbygoogle || []).push({});

--------------------------------------…

(a) Find the equation of the line l through P(1, 1, 2) and Q(1, 0, 4) in vector, parametric and Cartesian forms.

(b) Find the vector form of the line k through R(0, 3, 1) which is perpendicular to l.

(c) Find the Cartesian form of the plane containing the lines l and k.

(d) Find the vector form of the line through T(0, 0, 3) which is normal to this plane.

--------------------------------------…

so i guess i did the first bit alright : cartesian : z=6+4x , y=6

for the second one i got this line : (-5,4,2)+t(28,-37,7) , i timed it by 17 to get rid of the denominator

third part : the lines seem to have no intersection so i am stuck!

appreciate it if anyone can help out
