Question

Liven the line.
( k x+3 y+1=0 )
( 2 x+y+5=0 ) ane bonjugate
with respelt to ( x^{2}+y^{2}-2 x-4 y-4=0 )
( leqslant 0 )
( (k x+3 y-1)(2 x+y+5)=x^{2}+y^{2}-2 x-4 y-4 )
equating Hue Coelslivient ob ( x^{2} )
( Rightarrow quad 2 k=1 )
( k=1 / 2 )

# 1.5.1 5=0 are conjugate lines with respect to the circle 12. Find the value of k if kx + 3y-1=0, 2x + y +5=0 are conjugate lines with re x+y - 2x - 4y – 4=0. -&- are conjugate with respect to the circle com
