You can put this solution on YOUR website!
\"+y+=+x%5E2+%2B+2x+-+7+\"
\n" ); document.write( "You need to get a big picture of it.
\n" ); document.write( "What you've got is
\n" ); document.write( " y = ( some terms with \"x\" in them ) - 7
\n" ); document.write( "---------------------------------
\n" ); document.write( "The \"+-7+\" just pulls \"+y+\" negative
\n" ); document.write( "by the same amount, \"-7\"
\n" ); document.write( "for each value of \"x\" that you plug into
\n" ); document.write( "the right side.
\n" ); document.write( "------------
\n" ); document.write( "I'll do 3 plots:
\n" ); document.write( "\"+y+=+x%5E2+%2B+2x+\"
\n" ); document.write( "\"+y+=+x%5E2+%2B+2x+-+7+\"
\n" ); document.write( "\"+y+=+-7+\"
\n" ); document.write( "---------
\n" ); document.write( "
\n" ); document.write( "See how the straight line \"+y+=+-7+\" pulls down \"+y+=+x%5E2+%2B+2x+\"?
\n" ); document.write( "
\n" );
