Scalar equations such as y=2x+3 actually generate POINTS which are collinear. A vector equation, as the name implies, generates VECTORS, and these vectors are definitely NOT COLLINEAR.
How then can we say that an equation such as
r = (2,1,3) + t(1,2,4) is the "equation of a line"?
Also, why is it not possible to produce a scalar equation for a line in 3-D?
