Given line and plane are
\(\frac{x-1}{3}=\frac{y}{2}=\frac{z+1}{7}=\lambda\, .....(i)\)
and x + y + z = 8 ....(ii)
Let Q \((\alpha, \beta, \gamma)\) be point of intersection of equation (i) and (ii),
'Q' lie on line (i)
Also Q \((\alpha, \beta, \gamma)\) lie on plane (ii),
Required equation of line passing through P(4, 6, 2) and Q (-8, -6, -22) is
