\n" ); document.write( "if a line has no $\"x-intercept\"$ then it is $\"parallel\"$ to $\"y-axis\"$ -the line is a horizontal line
\n" ); document.write( "or if a line has no $\"y-intercept\"$ will be when the line is parallel to $\"x-axis\"$ -the line is a vertical line\r
\n" ); document.write( "\n" ); document.write( "If you think of the $\"y-scale\"$ as temperatures in Kelvin above absolute zero, and the $\"x-scale\"$ as time after the big bang there would be no intercepts.\r
\n" ); document.write( "\n" ); document.write( "another a real-life situation where a graph would have no $\"x\"$ - or $\"y-intercept\"$ is a hyperbola, $\"xy+=+c\"$ (some constant)\r
\n" ); document.write( "\n" ); document.write( "or, the gravitational force between two different planets (where $\"x\"$ is the distance between the centers, and $\"y\"$ is the force); there is no $\"y-intercept\"$ because this would imply that two planets are at the same point in space, and there is no $\"x-intercept\"$ because the planets would have to be infinitely far for there to be $\"zero\"$ gravitational force\r
