find the variation constant and an equation where y varies directly as x
\n" ); document.write( "y = kx
\n" ); document.write( ":
\n" ); document.write( "y=12 when x=2
\n" ); document.write( "12 = 2k
\n" ); document.write( "k = \"12%2F2\"
\n" ); document.write( "k = 6; is the constant
\n" ); document.write( ":
\n" ); document.write( "y = 6x
\n" ); document.write( "
\n" );
