Show students the table of values in the middle and ask what they might look like plotted.[br]Show the values plotted using the check box on the left.[br]Ask students how they could use the graph to predict/extrapolate values?[br]Would there be a better way to do things? What if the model could be forced to become linear?[br]Show the values in the lower table and plot these by using the check box on the right before looking at how to rearrange the algebraic model to its linear form.
