Let require point is P, then by section formula the coordinate of point P are

$$\begin{gathered} \Rightarrow \mathrm{p}\left(\frac{{\mathrm{mx}}_2 + {\mathrm{nx}}_1}{\mathrm{m} + \mathrm{n}}, \frac{{\mathrm{my}}_2 + {\mathrm{ny}}_1}{\mathrm{m} + \mathrm{n}}, \frac{{\mathrm{mz}}_2 + {\mathrm{nz}}_1}{\mathrm{m} + \mathrm{n}}\right) \\ \Rightarrow \mathrm{p}\left(\frac{- 4 + 9}{2 + 3}, \frac{6 - 6}{2 + 3}, \frac{22 + 3}{2 + 3}\right) \\ \Rightarrow \mathrm{p}\left(\frac{5}{5}, \frac{0}{1}, \frac{25}{5}\right) \\ \Rightarrow \mathrm{p}\left(1, 0, 5\right) \end{gathered}$$
