You can put this solution on YOUR website! In 1993, the life expectancy of males in a certain country was 62.7 years. In 2000 it was 65.5 years. what will the life expectanncy be in 2009?
-----
You have 2 points:(0,62.7) and (7,65.5) where the x-value is
# of years after 1993.
-----
slope = (65.5-63.7)/7 = 0.2571
-------
Equation:
life exect = 0.2571(yrs after 1993) + 62.7
-----------------------
le = 0.2571(16) + 62.7
le = 66.81 yrs
