Answer» ` (( 2 )/( 3),( 1 ) /( 3)) ` and LINE, ` ax+ by+c= 0 ` ` rArr3ax+ 3by+3c =0 ""`… (II) On subtractingEq.(i)from Eq.(ii),weget ` ( 3x-2 ) a+(3y- 1 )b = 0 * a +0* b ` On comparingbothsides , we get `3x- 2= 0rArrx=(2 )/( 3 ) ` `and3y- 1= 0rArry=( 1 ) / (3 ) ` `therefore`Line`ax+by+ c =0 `passesthroughthefixedpoint` (( 2 ) /( 3 ) , ( 1 ) /( 3 ) ) ` |
