<PRE><B>Question 308777</B>
In 1990, the life expectancy of males in a certain country was 62.1 years,
1996 it was 65.3 years. 
-----
slope = (65.3-62.1)/(6) = 3.2/6 = 0.5333
intercept = 62.1

-------------------------

Let E represent life expectancy in year T and let t represent the number of years since 1990. E(t)= [ ]t+[]
---
E(t) = 0.5333t + 62.1
===========================
 use the function to predict the life expectancy of males in 2006. E(16)= [ ]
E(16) = 0.5333(16) + 62.1 = 70.63333
==========================================
