If $\vec{v}_1 = \left[\begin{array}{c} -3\cr 1 \end{array}\right]$ and $\vec{v}_2=\left[\begin{array}{c} -3\cr 3 \end{array}\right]$ are eigenvectors of a matrix $A$ corresponding to the eigenvalues $\lambda_1=5$ and $\lambda_2=-3$, respectively,

then $A(\vec{v}_1 + \vec{v}_2) =$ $\left[\Rule{0pt}{2.4em}{0pt}\right.$$\left]\Rule{0pt}{2.4em}{0pt}\right.$

and $A(-3 \vec{v}_1)=$ $\left[\Rule{0pt}{2.4em}{0pt}\right.$$\left]\Rule{0pt}{2.4em}{0pt}\right.$
