Given the vectors

\vec{a}

,

\vec{b}

, and

\vec{c}

shown in the picture, express the vector

\vec{c}

as a linear combination of vectors

\vec{a}

and

\vec{b}

.

\vec{c} = - \vec{a} - 2 \vec{b}

\vec{c} = - \vec{a} + \frac{1}{2} \vec{b}

\vec{c} = - 2 \vec{a} - \vec{b}

\vec{c} = 2 \vec{a} + \frac{3}{2} \vec{b}
