m represents male life expectancy and 

F represents female life expectancy.

(m, F) represent the points on the line.


(48, 51) and (75, 80) are points on the line.

So, slope of the line is



We can use the point slope form of a line to find the equation of the line

The point slope form is


where M is the slope of the line

and  is a point on the line.

Here M = 29/27  and

take   = (48, 51)


So, equation of the line is

 


So, equation is

F(m) =  1.07m - 102.56
