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.

i believe it is b. what was the cause of the big bang

hope this !

dopamine..

"it was found that some people who were taking the drug l-dopa to raise their levels of dopamine were developing schizophrenic-like symptoms supporting research a strength of the dopamine hypothesis is that there are many studies which have shown support for the neurochemical explanation."
