The plane $2x - (1 + λ)y + 3λz = 0 $ passes through the intersection of the planes
Answer & explanation
Correct answer: option 2
The equation of the given plane can be written in the form (2x - y) + λ(-y + 3z) = 0 which is a plane passing through the intersection of the planes 2x - y = 0 and -y + 3z = 0.
