Question 387068: this is a tough one!
In 1994 the life expectancy of males in a certain country was 63.5 years. In 1999, it was 66.9 years. Let E represent the life expectancy in year t and let t represent the number of years since 1994.
The linear fuction E(t) that fits the data is
E(t)=_t+_ (round to the nearest)
Use the function to predict the life expectancy of males in 2008.
E(14)=_
