Question 156550: In 1994, the life expectancy of males in a certain country was 69.6 years. In 2001, it was 73.3 years. Let E represent the life expectancy in year t and let t represent the number of years since 1994.
The linear function E(t)that fits the data is,
E(t)= t+
(Round to the nearest tenth.)

In 1994, the life expectancy of males in a certain country was 69.6 years.
In 2001, it was 73.3 years.
Let E represent the life expectancy in year t and let t represent the number of years since 1994.
----------------------
You have two points(0,69.6) (7.73.3)
slope = (73.3-69.6)/(7-0) = 0.5286
intercep = 69.6
The linear function E(t)that fits the data is,
E(t)= 0.5296t + 69.6
----------------------------
(Round to the nearest tenth.)
