The equation of the plane passing through the line of intersection of the planes \(x+y+z=1\) and \(3 x+4 y+5 z=2\) and perpendicular to the XY- plane is
- A \(2 x+y-3=0\)
- B \(x-2 y+3=0\)
- C \(x-3 y-2=0\)
- D \(2 x-y+6=0\)
Answer & Solution
Correct Answer
(A) \(2 x+y-3=0\)
Step-by-step Solution
Detailed explanation
\((x+y+z-1) + \lambda (3x+4y+5z-2) = 0\) \((1+3\lambda)x + (1+4\lambda)y + (1+5\lambda)z - (1+2\lambda) = 0\)
