y-3=0
\n" ); document.write( "

\r\n" );
document.write( "Solve it for y\r\n" );
document.write( "\r\n" );
document.write( "y = 3\r\n" );
document.write( "\r\n" );
document.write( "That's the same as\r\n" );
document.write( "\r\n" );
document.write( "y = 0x + 3\r\n" );
document.write( "\r\n" );
document.write( "[That's hard to recognize because the 0x is understood, not written]\r\n" );
document.write( "\r\n" );
document.write( "Compare it to\r\n" );
document.write( "\r\n" );
document.write( "y = mx + b\r\n" );
document.write( "\r\n" );
document.write( "So it has a slope of m=0, and y-intercept of (0,b) = (0,3).\r\n" );
document.write( "\r\n" );
document.write( "So it is a horizontal line with y-intercept (0,3)\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "Since it is horizontal it is parallel to the x-axis, and will\r\n" );
document.write( "never intersect it.  Therefore it has only a y-intercept (0,3)\r\n" );
document.write( "and it has no x-intercept. \r\n" );
