Let \( \mathrm{P} \) be a plane containing the line \( \frac{x-1}{3}=\frac{y+6}{4}=\frac{z+5}{2} \) and parallel to the line
\( \mathrm{P} \)
IV
\( \frac{x-1}{4}=\frac{y-2}{-3}=\frac{z+5}{7} \). If the point \( (1,-1, \alpha) \) lies on the plane \( P \), then the value of \( |5 \alpha| \) is equal to
