Draw a trend line for the scatter plot. Use the following scatter plot of the ordered pairs as an example.

Collect, organize, and analyze data.
Make predictions based on data.
According to the U.S. Food and Drug Administration, 30% of daily calories should come from fats and only 10% from saturated fats. Based on a 2,000-calorie-a-day intake, this translates to about 600 calories from fat and 20 grams of saturated fat.

By knowing the number of fat calories in a fast food item, can you predict the number of grams of saturated fat?

Your task:

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 . Organize your data in a table.

II. Make a scatter plot of the data on graph paper. Be sure to label the axes and use an appropriate title for the graph.
You may wish to use a graphing calculator, spread sheet, or other technology resource to aid you in graphing.

Create a Graph

III. Draw a trend line for the scatter plot. Use the following scatter plot of the ordered pairs as an example.

IV. Calculate the slope of the trend line.
