i need help with graphing inequalities using my ti-84.

\r\n" );
document.write( "Soppose you have \r\n" );
document.write( "\r\n" );
document.write( "4x+y > 5\r\n" );

document.write( "\r\n" );
document.write( "Press Y=\r\n" );
document.write( "\r\n" );

document.write( "\r\n" );
document.write( "To the right of \Y2= type 2x-3\r\n" );
document.write( "\r\n" );
document.write( "Now press ZOOM then 6 and you will see two\r\n" );

document.write( "But you want them shaded.  \r\n" );
document.write( "\r\n" );
document.write( "Press Y= again\r\n" );
document.write( "\r\n" );
document.write( "Now you have to learn about the back-slash\r\n" );
