	Two-Point Form

The points

on a line passing through two points $P\ne Q$ can be described in the following form:

$\displaystyle \overrightarrow{PX} = t\overrightarrow{PQ}, \quad t\in\mathbb{R}\, ,$

where parameter values $t\in[0,1]$ correspond to the points of the line segment $\overline{PQ}$ .

Correspondingly, for the coordinates of the vector $\vec{x}$ we have

$\displaystyle x_i = p_i + t(q_i-p_i),\quad i=1,2,3\, .$
