The gradient of an interval

The gradient of an interval between 2 points is defined as "rise over run". Drag the red points and then use the blue slider to reveal the solution.
Investigate possible values of the gradient - what does a positive/negative gradient mean? When is the gradient zero? When (and why) is the gradient undefined? Drag the blue line around and investigate how the gradient changes - is this what you would expect?
