Question 333920
In 1993, the life expectancy of males in a certain country was 65.8 years. In 1998, it was 68.2 years. Let E represent the life expectancy in year t and let t represent the number of years since 1993.
---
You have 2 points: (0,65.8) and (5,68.2)
--------------------------------------------- 
Below is the queation.
The linear function E(t) that fits the data is?: 
slope = (68.2-65.8)/(5-0) = 2.4/5 = 0.48
---
t-intercept = f(0) = 65.8
--------------------------------
Equation:
E(t) = 0.48t+65.8

E(t)= ? t+ ?
