The value of k, such that 
lies in the plane 2x – 4y + z = 7 is -
Text Solution
Verified by ExpertsThe correct answer is:
A
It is evident that the normal to the plane is perpendicular to the given line. Hence the plane is parallel to the line. If the line lies in the plane then any point on the line must lie in the plane. Hence (4, 2, k) must satisfy the equation of the plane
⇒ 8 – 8 + k = 7
