Given the vectors \( \overrightarrow{a} \), \( \overrightarrow{b} \), and \( \overrightarrow{c} \) shown in the picture, express the vector \( \overrightarrow{c} \) as a linear combination of vectors \( \overrightarrow{a} \) and \( \overrightarrow{b} \).
\( \overrightarrow{c} = -\overrightarrow{a}-2\overrightarrow{b} \)
\( \overrightarrow{c} = -\overrightarrow{a} + \frac12 \overrightarrow{b} \)
\( \overrightarrow{c} = -2\overrightarrow{a} - \overrightarrow{b} \)
\( \overrightarrow{c} = 2\overrightarrow{a} + \frac32 \overrightarrow{b} \)
