Daily fat consumption According to the US Department of Agri

Daily fat consumption. According to the U.S. Department of Agriculture, the daily fat consumption F per person can be approximated by F = 190 + 0.8t (grams) where t is the number of years after 2000. • a. What is the slope of the line? • b. What does the slope represent?

Solution

T a) The equation of straight line is of the form: y = mx + c

where m = slope and c = y-intercept.

F = 190 + 0.8t is of the form y = mx + c

Comparing we find m = 0.8

So, slope = 0.8

b) The slope represents the the rate at which a change in the value of \'t\' produces a change in the value of \'F\'.
