In 1992, the life expectancy of males in a certain country was 73.5 years. In 1996, it was 75.7 years. Let E representthe life expectancy in yeart and let t represent number of years since 1992.

Fill in the linear function E(t) that fits the data
E(t)=____t+____

uses this to prdict the life expectancy of males in 2009

E(17)=____

unsure what to do here I do not get the question.

• math-word problem -

You are making a linear math model for life expectancy.

slope= (75.7-73.5)/73.5

e(t)=slope*t+b

b will equal 73.5 check that.

To find the slope would it then be 75.7-73.5/73.5
so the slope would be 33.4?
