Line of Best Fit

The cost of chips is going up, while the percentage of voters is going down. Your learners will be able to predict different outcomes when creating a graph with a line of best fit. Using a graphing calculator or not, they can create the line from the data and then use that slope to predict future results. The activity encourages explanation of answers, which can be used for class discussion.
