>>You can repeat "The derivative is the slope of the curve" until you're blue in the face but some people just won't 'get it'. Then you have to explain why the slope of a line is significant. For example if you have the position of something in the form of an equation you can take the derivative and get the velocity. Anybody who understands why the slope of the line is interesting will fair far better.beyond that the area under the curve of a velocity graph will give you the distance traveled.
