<PRE><B>Question 145258</B>
In 1991, the life expectancy of males in a certain country was 70.6 years. In 1997 it was 73.7 years. Let E represent the life expectancy in year t and let t represent the number of years since 1991 
here is what I came up with but I am not sure if I am right
--------------- 
The first data point is ( 0, 70.6)
Comment: This is the y-intercept; you only need to find the slope.
-------
the second data point is ( 6, 73.7)
-------
slope = (73.7-70.6)/(6-0) = 31/60 = 0.5167
------
EQUATION:
E(t) = 0.5167t + 73.7
