\r\n" );
document.write( "y varies directly with x.  So we write\r\n" );
document.write( "\r\n" );
document.write( "y = kx\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "We can see that when x=6 and y=5, the equation\r\n" );
document.write( "5x-6y=0 is true, for 5(6)-6(5)=0\r\n" );
document.write( "\r\n" );
document.write( "So we substitute these values in\r\n" );
document.write( "\r\n" );
document.write( "y = kx\r\n" );
document.write( "\r\n" );
document.write( "5 = k(6)\r\n" );
document.write( "\r\n" );
document.write( "Divide both sides by 6\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "Therefore replacing k by  in y=kx we have\r\n" );

document.write( "y = x\r\n" );
