Consider the set all lines px + qy + r = 0 such that 3p + 2q + 4r = 0. Which one of the following statements is true ?
A
The lines are not concurrent
B
The lines are all parallel
C
The lines are concurrent at the point 
D
Each the line passes through the origin.
Text Solution
Verified by ExpertsThe correct answer is:
C
Sol. Given relation is 3p + 2q + 4r = 0
⇒ 
p + 
+ r = 0 ...........(ii)
comparing and we get x = 
, y = 
hence we can say that these lines are concurrent at
