I noticed that most students in my Physics class
have graphing calculators too.  The TI calculators
have data analysis functions that will find the
constants a and b in the equations

Linear    Y = a + bX
Log       Y = a + b*ln(x)
Exp       Y = ab^x
Power     Y = aX^b

Data can be taken for X and Y, then is entered
into the stat matrix, then the regression function
calculates the a and b.

The stat matrix can also be used to plot a scatter
graph and the regression equation can be plotted
over the data points.

Typically the graphing calculators are used in
Pre Calc and Calc.  The data analysis functions
may need to be taught to the students.
