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 \( \vec{b} \).
\( \vec{c} = -2\vec{a} + \vec{b} \)
\( \vec{c} = -\vec{a} + \frac12\vec{b} \)
\( \vec{c} = -\frac32\vec{a} + \vec{b} \)
\( \vec{c} = -2\vec{a} + \frac32\vec{b} \)
