If y varies directly as x, then it fits a formula,
\n" ); document.write( " $\"y=kx\"$
\n" ); document.write( "From your examples,
\n" ); document.write( " $\"16=k%2820%29\"$
\n" ); document.write( " $\"k=16%2F20=4%2F5\"$
\n" ); document.write( " $\"y=%284x%29%2F5\"$
\n" ); document.write( "When x=5, then
\n" ); document.write( " $\"y=%284x%29%2F5\"$
\n" ); document.write( " $\"y=%284%285%29%29%2F5\"$
\n" ); document.write( " $\"y=4\"$ \n" ); document.write( "

\n" );
