Question 1181927: Assume that the real-world context can be accurately modeled with a linear function.
Between 1900 and 2003, the life expectancy for men and women in the United States increased dramatically. For men, life expectancy increased from 48 to 75 years. For women, life expectancy increased from 51 to 80 years.†
Model male life expectancy M as a function of female life expectancy f. (Round your coefficients to two decimal places.)

The year names are not important. Just the life expectancies. 
LIFE EXPTCTANCIES

MALE        48       75

FEMALE      51       80

If y for males
and x for females
Points are (51,48) and (80,75).

You now have two points as (x,y). Use the two points to find equation and finish in slope-intercept form.
