Take Note: Consider modeling the data in the table.
Classify each year in the left column below based on whether estimating cheese consumption that year is an example of interpolation or extrapolation.

Problem 4 Got It?
Create a table at desmos.com and use it to find a linear regression model of the cheese consumption data. Let x = years since 1900. Recall Desmos' linear regression notation: y1~ax1+b.
Zoom and pan your graph to establish an appropriate viewing window that contains all data points and the regression line.
Take a screenshot of your graph and upload or paste it to the Formative canvas.

Problem 4 Got It? Use the model you created above to estimate cheese consumption for 1980, 2000, and 2012 algebraically and/or graphically. Remember that you were instructed to let x represent years since 1900.
Also, identify the prediction years in which you can have the most and least confidence.
Hint: Consider interpolation vs extrapolation.
