Activity 1 - generating regression: for each data set, plot a scatterplot and find the
regression equation y = ab- and determine whether the data shows exponential growth or decay.
then, use the r-value to determine if the regression equation is a good fit for the data. "remember to
turn diagnostics on in your graphing calculator in order to get the r-value and plots on to see the scatterplot
