Hello What do i need to do to describe the following subspaces of $\displaystyle R^3$ $\displaystyle \left<{(1,1,1,)}\right>$ $\displaystyle \left<{(1,2,3), (3,2,1,), (-2,-2,-2)}\right>$ Thanks

I assume you actually mean "the subspaces spanned by the vectors ...". Every subspace of $\displaystyle R^3$ is, geometrically, either 1) a line through the origin 2) a plane containing the origin 3) all of $\displaystyle R^3$. Which are these?
