Think about it, what number multiplied by 0 gives me 5? There is no such number and dividing by 0 is not possible. So in this case there is no slope or the slope is undefined. Since this is a vertical line, it is parallel to the y-axis. Since parallel lines never intersect, there is no y-intercept. Hope this makes sense. </SPAN>\n" );
