Express the line L in ?³ spanned by the vector ? = ?1, 1, 1? as the image of a matrix A and as the kernel of a matrix B. In other words, find a matrix A such that im(A) = span(?) and also find a matrix B such that ker(B) = span(?).

Consider vectors $\vec{v}_{1}, \vec{v}_{2}, \vec{v}_{3}$ in $\mathbb{R}^{4} ;$ we are told that $\vec{v}_{i} \cdot \vec{v}_{j}$ is the entry $a_{i j}$ of matrix $A$. Find proj $_{V}\left(\vec{v}_{1}\right),$ where $V=\operatorname{span}\left(\vec{v}_{2}, \vec{v}_{3}\right) .$ Express your answer as a linear combination of $\vec{v}_{2}$ and $\vec{v}_{3}$
