Answer 1

First we need to figure out what direction that line is going in. I suggest letting x = t, and finding out what y and z are in terms of t. Basically we need to get a prametric form of the line so we can get the direction of it easily.

Answer 2

i agree ^^
i came up with
x = 2t
y = 3t-1
z = t-4

so directional vector is <2,3,1>
