-- From the 1st to the 2nd column:
Fat increased by 5 grams
Calories increased by 70 = 14 more calories per each additional gram of fat.
-- From the 2nd to the 3rd column:
Fat increased by 2 grams
Calories increased by 28 = 14 more calories per each additional gram of fat.
-- From the 3rd to the 4th column:
Fat increased by 8 grams
Calories increased by 112 = 14 more calories per each additional gram of fat.
-- From the 4th to the 5th column:
Fat increased by 3 grams
Calories increased by 42 = 14 more calories per each additional gram of fat.
Each time the grams of fat increase, the calories increase by 14 calories
per additional gram. So the data represent a linear relationship, and the
rate of change is 14 calories per gram of fat.
