if a line has no x-intercept then it is parallel to y-axis-the line is a horizontal line
or if a line has no y-intercept will be when the line is parallel to x-axis-the line is a vertical line
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.
another a real-life situation where a graph would have no x- or y-intercept is a hyperbola, xy+=+c(some constant)
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
