In 1990, the life expectancy of males in a certain country was 68.4 years and 71.7 years in 1996. Let E represent the life expectancy in year t represent the number of years since 1990. The linear equarion E(t) that fits that data is E (t)= __+__
round to the nearest tenth/
---------------------------------------
You have two points: (0,68.4) and (6,71.7)
---
slope = (71.7-68.4)/(6-0) = 0.55
Note: (0,68.4) gives the y-intercept.
-------------
Equation: E(t) = 0.55t + 68.4
=====================================
