The domain is the range of numbers which x can equal. There are two different domains that linear equations can have. <BR>\n" );
document.write( "<br>Although linear equations are always shaped as a line, usually giving an infinite range of x, there is one exception. If the equation is x=1, x=2, and so on, x can only be one number, and therefore the domain only contains one number.<BR>\n" );
