Let P be a plane $\displaystyle l x+\mathrm{m} y+\mathrm{n} z=0$ containing the line, $\displaystyle \frac{1-x}{1}=\frac{y+4}{2}=\frac{z+2}{3}$. If plane P divides the line segment AB joining points $\displaystyle \mathrm{A}(-3,-6,1)$ and $\displaystyle \mathrm{B}(2,4,-3)$ in ratio $\displaystyle \mathrm{k}: 1$ then the value of k is equal to:
