Dear Tapasranjan


 let the equation of the line passing through (1,1,1) and parallal to the plane 2x+3y+z+5=0  is


(x-1)/a  = (y-1)/b = (z-1)/c


wher a,b,c are the direction ratios of line.


and given direction ratios  of the normal of the plane is 2,3,1


so a*2 + b*3 + c*1 =0


for different combination of a,b,c different line are posible so infinite lines are possible.


for example for c=1 a=1 b=-1 one line is possible


Please feel free to post as many doubts on our discussion forum as you can.
 If you find any question Difficult to understand - post it here and we will get you the


answer and detailed solution very quickly.
