y=3/5x + 1/4 intersects the line y=-1/8x + r at the point (-1/2,-1/20)
\n" ); document.write( " the intersection point -(1/2,-1/20) lies on both the lines.hence
\n" ); document.write( "y=-1/8 x + r should be satisfied by (-1/2,-1/20)..substituting
\n" ); document.write( "-1/20=(-1/8)*(-1/2)+r
\n" ); document.write( "r=-1/20-(1/16) = -[(4+5)/80]=-9/80\r
\n" ); document.write( "\n" ); document.write( " \n" ); document.write( "

\n" );
