Linear Functions

[bond007]

I don't have a clue as how to set this problem up or solve it. I need help asap! In 1994, the life expectancy of males in a certain
country was 67.1 years. In 1998, it was 70.2 years. Let E represent the life expectancy in year t and let t represent the number
of years since 1994.

The linear E(t) that fits the data is:
E(t) = __t + ___

Use the function to predict the life expectancy of males in 2008.
E(14)

What is the linear function?

What is the linear function?

You are given two points : (0,67.1) and (4,70.2) ? counting 1974 as the 0 th year.

You need to draw a straight line (linear) through these two points.

Now tell us what is the equation of the line passing through (x[sub:215kytiw]1[/sub:215kytiw], y[sub:215kytiw]1[/sub:215kytiw]) and (x[sub:215kytiw]2[/sub:215kytiw],y[sub:215kytiw]2[/sub:215kytiw])?

Use the equation......
