I know that for two points, the difference between them is a line segment
lets say these two points are 'a' and 'b' respectively, so b-a = "new vector represent the line"
In my textbook b-a=d*t -- where 'd' is a vector along the directon of 'b-a' and t is a parameter.
does 'd' actually represent the unit vector of the line? or it's just an arbitrary line with the same direction?
