Point-Slope Form


A B C D E F G H I J K L M N O P Q R S T U V W X Y Z overview

The points $ X$ on a line through $ P$ in direction $ \vec{u}$ can be described in parametric form by

$\displaystyle \overrightarrow{PX} = t\vec{u},\quad
t\in\mathbb{R}\,.
$

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

$\displaystyle x_i = p_i + tu_i,\quad i=1,2,3\,
.
