Question and answer
If a line has no y-intercept, what can you say about the line? What if a line has no x-intercept? 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?
A line that has no y-intercept is a vertical line. A line that has no x-intercept is a horizontal line. A real life situation would be: 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. ]
