slope= 69-65.7 divided by 6 years
E(t)= slope*t+ b
To find b, put in 1994, the slope, t=0, and you have b. (65.7)
In 1994, the life expectancy of males in a certain country was 65.7 years. In 2000, it was 69.0 years. Let E represent the life expectancy in year t and let t represent the number of years since 1994
the linear function E(t) that fits the data is
E(t)=?t+?
use the function to predict the life expectancy of males in 2007?
E(13)=?
