#### Answer

$\textbf{r} = \langle -3,2,-1\rangle + t\langle 1,-2,0 \rangle$

#### Work Step by Step

Equation of a Line: $\textbf{r} = \textbf{r}_0 + t\textbf{v}$
$\textbf{r}_0 = \langle -3,2,-1\rangle$
$\textbf{v} = \langle 1,-2,0 \rangle$
$\textbf{r} = \langle -3,2,-1\rangle + t\langle 1,-2,0 \rangle$
