$\stackrel{\mathbf{\rightharpoonup}}{\mathbf{B}}\mathbf{=}\mathbf{1}\hat{\mathbf{i}}\mathbf{}\mathbf{-}\mathbf{}\mathbf{1}\hat{\mathbf{j}}$

$\mathbf{2}\stackrel{\mathbf{\rightharpoonup}}{\mathbf{B}}\mathbf{=}\mathbf{2}\hat{\mathbf{i}}\mathbf{}\mathbf{-}\mathbf{}\mathbf{2}\hat{\mathbf{j}}$

$\stackrel{\mathbf{\rightharpoonup}}{\mathbf{A}}\mathbf{=}\mathbf{4}\hat{\mathbf{i}}\mathbf{+}\mathbf{2}\hat{\mathbf{j}}$

$\mathbf{0}\mathbf{.}\mathbf{5}\stackrel{\mathbf{\rightharpoonup}}{\mathbf{A}}\mathbf{=}\mathbf{2}\hat{\mathbf{i}}\mathbf{+}\mathbf{1}\hat{\mathbf{j}}$

Draw the vector $\overrightarrow{\mathbf{C}}\mathbf{=}\mathbf{0}\mathbf{.}\mathbf{5}\overrightarrow{\mathbf{A}}\mathbf{-}\mathbf{2}\overrightarrow{\mathbf{B}}$.

The length and orientation of the vector will be graded. The location of the vector is not important.
