\overrightarrow{AB} = \overrightarrow{OB}-\overrightarrow{OA} = \left(\begin{array}{c} 0-2 \\ 9-(-1) \\ -3-4\end{array}\right) = \left(\begin{array}{c} -2 \\ 10 \\ -7\end{array}\right)

\overrightarrow{AC} = \overrightarrow{OC}-\overrightarrow{OA} = \left(\begin{array}{c} -2-2 \\ 5-(-1) \\ 1-4\end{array}\right) = \left(\begin{array}{c} -4 \\ 6 \\ -3\end{array}\right)
