Correct. A typical way of expressing that freedom is :\[x_{1}=t\]\[x_{2}=t\]\[x_{3}=t\]\[t\in R\]in geometric terms that's a line in the direction of the vector :\[\left[\begin{matrix}1 \\ 1\\1\end{matrix}\right]\]or written as :\[t\left[\begin{matrix}1 \\ 1\\1\end{matrix}\right]\]so you select a point on the line by choosing a value for t
