Question 717201

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
