There was a common notational error between the unit vector coefficients
and unit vector coordinates. The unit vectors, i,j and k are actually
vectors (1,0,0), (0,1,0) and (0,0,1) respectively. 3i, for example, means
3*(1,0,0). The "x-coordinate" is x=3.
The final problem asks for points of intersection. Most of you solved for
the scalor multiple, t, at which the point of intersection occurs but failed
to plug that value back into the equation of the line to find the actually
point of intersection.
