Consider the vector \(\overrightarrow{P_0P} = \vec{p} - \vec{p_0}\) which has its tail at \(P_0\) and point at \(P\). Then, letting \(t\) be a parameter, we can write \(L\) as \[\begin{array}{ll} \left. Added Dec 18, 2018 by Nirvana in Mathematics. Free line intersection calculator. This app is really good. a=5/4 To see this, replace \(t\) with another parameter, say \(3s.\) Then you obtain a different vector equation for the same line because the same set of points is obtained. This is the form \[\vec{p}=\vec{p_0}+t\vec{d}\nonumber\] where \(t\in \mathbb{R}\). If we know the direction vector of a line, as well as a point on the line, we can find the vector equation.
