What special meaning does the slope of a graph of mass versus volume have

The slope represents the density of the substance been represented using the graph

Explanation:

The slope of a graph is calculated as the change in the y axis divided by the change in the X axis  which is known dy/dx  in the above question the Y axis is represented by the Mass of the substance and the X axis is represented by the volume of the substance hence

the change in mass ( dy ) / change in volume ( dx ) = density ( average ) of the substance. therefore the special meaning of the slope is that it represents the density of the substance being represented using the graph.

another example of kinetic energy would be,

kinetic energy   >     moving energy
