Answer

$\mathbf{x}=\begin{bmatrix}x_{1}\\x_{2}\end{bmatrix}=\begin{bmatrix}-2\\0\end{bmatrix}+t\begin{bmatrix}-5\\6\end{bmatrix}$ where t represents a parameter.

Work Step by Step

$\mathbf{a}=\begin{bmatrix}-2\\0\end{bmatrix}$ $\mathbf{b}=\begin{bmatrix}-5\\6\end{bmatrix}$ let $t$ represent a parameter. The line will go through $a$ parallel to $t*b$. $\mathbf{x}=\begin{bmatrix}x_{1}\\x_{2}\end{bmatrix}=\begin{bmatrix}-2\\0\end{bmatrix}+t\begin{bmatrix}-5\\6\end{bmatrix}$
