Two straight lines passing through the point \[A(3,2)\] cut the line \[2y=x+3\] and x-axis perpendicularly at P and Q respectively. The equation of the line PQ is
A)\[7x+y-21=0\]
B)\[x+7y+21=0\]
C)\[2x+y-8=0\]
D)\[x+2y+8=0\]
Correct Answer:
A
Solution :
[a] \[\because \] Coordinate of Q are (3, 0) & it passes through PQ. \[\therefore \]Putting the values of \[(x=3)\And (y=0)\]is options we get. Equation of line \[PQ=7x+y-21=0\]
