A) The lines are not concurrent
B) The lines are concurrent at the point\[\left( \frac{3}{4},\,\,\frac{1}{2} \right)\]
C) The lines are all parallel
D) Each line passes through the origin
Correct Answer: B
Solution :
Given lines are \[px\text{ }+\text{ }qy\text{ }+\text{ }r\text{ }=\text{ }0\,\,\,\,\,\,.......\,(1)\] \[\And \,\,\,3p\,\,+\,\,2q\,\,+\,\,4r\,\,=\,\,0\text{ }...\text{ }\left( 2 \right)\] \[\therefore \] (2) can be written as \[\frac{3}{4}p\,\,+\,\,\frac{q}{2}\,+\,r\,\,=\,\,0\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,......\,(3)\] from (a) & (c) \[x\,\,=\,\,\frac{3}{4},\,\,\,\,y\,\,=\,\,\frac{1}{2}\]You need to login to perform this action.
