Question

How can we graph independent and dependent variables?

Answer 1

The independent variable should be plotted on the x-axis. The dependent variable should be plotted on the y-axis.

The graph of mass vs. volume places volume on the x-axis and the mass on the y-axis. The value of graphing this relationship is best understood by considering the following equation

`D=m/v`

Note the slope of your graph will be `(rise)/(run)` which is `(mass)/(volume)` which is the density of the material.
