\n" ); document.write( "\n" ); document.write( "\"3x-9y=-7\" \r
\n" ); document.write( "\n" ); document.write( "\"3x%2B7=9y\" \r
\n" ); document.write( "\n" ); document.write( "\"y=%283%2F9%29x%2B7%2F9\" \r
\n" ); document.write( "\n" ); document.write( "\"y=%281%2F3%29x%2B7%2F9\" -> the slope of this line is \"%281%2F3%29\"\r
\n" ); document.write( "\n" ); document.write( " the slope of a line perpendicular to this line will be negative reciprocal:\r
\n" ); document.write( "\n" ); document.write( "\"-%281%2F%281%2F3%29%29=-3\"\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "and the slope of a line parallel to this line will be same: \"%281%2F3%29\"\r
