You can put this solution on YOUR website!
does x vary directly with y or vice versa
\n" ); document.write( ":
\n" ); document.write( "if x varies directly as y then 3x=2y--->x/y=2/3.....so k=2/3
\n" ); document.write( "if y varies directly as x then 2y=3x--->y/x=3/2.....so k=3/2
\n" ); document.write( ":
\n" ); document.write( "the slope of y=3/5x is 3/5
\n" ); document.write( "
\n" );
