Question

During a certain flu epidemic, the total number T of patients diagnosed with the flu after d days is given in the table below.

d 0 5 10 15 20
T 35 41 47 53 59
(a) Check differences to show that these are linear data.
T is a not linear function.T is a linear function.    

(b) What is the practical meaning of the slope?
The slope represents the total number of cases each day.The slope represents the number of new cases per day.    


(c) Find the slope.


(d) Use a formula to express T as a linear function of d.
T =
