If \(l, m, n\) are in arithmetic progression, then the straight line \(l x+m y+n=0\) will pass through the point
- A \((-1,2)\)
- B \((1,-2)\)
- C \((1,2)\)
- D \((2,1)\)
Answer & Solution
Correct Answer
(B) \((1,-2)\)
Step-by-step Solution
Detailed explanation
Since, \(l, m, n\) are in AP. \[ \therefore \quad 2 m=l+n \] Given equation of line is \[ l x+m y+n=0 \] Now, assume that the point \((1,-2)\) satisfy the given equation.…
