Determine whether or not the set of vectors:

[tex]\left\{\bar{x}=t

\left(

\begin{array}{cc}1\\2\\1\end{array}

\right)

+s\left(

\begin{array}{cc}1\\1\\1\end{array}

\right)

+\left(

\begin{array}{cc}1\\0\\2\end{array}

\right),-\infty < t,s < \infty

\right\}[/tex]

is a subspace.

I really have no idea how to go about this. Do I just check if they are linear combinations of each other?
