Answer 2

I. Collect data from several fast food chains on the number of fat calories and grams of saturated fat in menu items. Record at least 12 ordered pairs of (fat calories, grams of saturated fat). Organize your data in a table.
IV. Calculate the slope of the trend line. (Choose two points on the line and find vertical change over horizontal change.)
V. Using the slope and y-intercept, write the equation of the trend line (y = mx + b).

VI. Choose a "calories from fat" value that is not in your collected data set and that is at least 10 fat calories away from any collected value. Use the equation calculated in step V to predict the number of fat grams in an item having that number of fat calories. Be sure to show your work.
