In 1995, the life expectancy of males in a certain country was 73.8 years. In 2001, it was 77.1 years. Let E represent the life expectancy in year t and let t represent the number of years since 1995.
---------------
Two points: (0,73.8), (6,77.1)
---------------
intercept = 73.8
slope = (77.1-73.8)/6 = 0.55
-------
The linear function E(t) thats fits the data is E(t)= 0.55t+73.8
