y varies inversely with x.

\r\n" );
document.write( "That says \r\n" );

\n" ); document.write( "when x is 3.5, y is 1.5
\n" ); document.write( "
\r\n" );
document.write( "Plug those in:\r\n" );
document.write( "\r\n" );
document.write( "\"1.5\"\"%22=%22\"\"k%2F3.5\"\r\n" );
document.write( "

\n" ); document.write( "what is the value of k, the constant of inverse variation?
\n" ); document.write( "
\r\n" );
document.write( "Solve for k.  Multiply both sides by 3.5\r\n" );
document.write( "\r\n" );
