Equation of straight line belonging to families of straight lines

\left( {x + 2y} \right) + \lambda \left( {3x + 2y + 1} \right) = 0

and

\left( {x - 2y} \right) + \mathrm{\mu }\left( {x - y + 1} \right) = 0

View answer and explanation

Correct option: B

5x - 6y + 4 = 0

Option B (

5x - 6y + 4 = 0

) is correct because it represents the equation of the straight line passing through the intersection points of the two families of lines.
