Question 618014: Think of a real-life situation where a graph would have no x- or y-intercept. Will what you say about the line always be true in that situation?
You can put this solution on YOUR website! e.g. 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.
