check the slopes; parallel lines have same slope\r

\n" ); document.write( "\n" ); document.write( "\"y-2x=+-5\" and \"2x-y=+-6\" in slope-intercept form \r
\n" ); document.write( "\n" ); document.write( "\"y=+highlight%282%29x-5\" and \"y=highlight%282%29x%2B6\" ...same slope; so, these two lines are parallel to each other\r
