If you have an equation you wish to plot:

You can calculate slope, intercept, and correlation coefficient from
worksheet data using SLOPE, INTERCEPT, and CORREL worksheet functions, or
compute more statistics using LINEST.

You have to be able to derive X and Y pairs from the equation, then plot
these pairs. A mathematician might recognize the general form of your
equation as being a particular shape, which would help you figure out where
to start populating your data range with numbers.
