Find the coordinates of the vectors \( \vec{u} \) and \( \vec{v} \) given by the picture and evaluate their dot product.
\( \vec{u}=(-3;6);\ \ \vec{v} =(-9;-6);\ \ \vec{u}\cdot\vec{v} = -9 \)
\( \vec{u}=(3;-6);\ \ \vec{v} =(9;6);\ \ \vec{u}\cdot\vec{v} = -9 \)
\( \vec{u}=(-3;6);\ \ \vec{v} =(-9;-6);\ \ \vec{u}\cdot\vec{v} = 9 \)
\( \vec{u}=(3;-6);\ \ \vec{v} =(9;6);\ \ \vec{u}\cdot\vec{v} = 0 \)
