let that line be  ax+ by + c= 0 


then acc to question  ( 2a + b + c ) + ( 3a+2b+c)+(-4a+7b+c) /√a²+b²+c²  = 0  by putting the values in the eq 


on solving it we get  a +10b +3c=0  or, c= -a/3 - 10b/3


so the eq becomes  ax +by -a/3-10b/3 = 0   or   a(3x - 1 ) + b (3y-10) = 0 


so the intersection point of the lines   3x-1=0  and   3y-10=0  is the given point

kya bits ke paper ke liye ncert book ko prefer kare ya koi dusari book ko considered kare
 
 
Hi, NCERT will just build the base. You need to study more and need to solve good question. Take any book that is targetted for JEE Advanced. That will do.
