Question

The number of fat grams f consumed daily by the average American can be approximated by f = 165 + 0.4t, where t is the number of years after 2000.+

Answer 1

Your equation is in the form y = mx + b except independent variable is t and dependent variable is f rather than y.

 

The slope is the coefficient of the dependent variable; m = 0.4
