Answer:
if what I think you want is the number of bachelor degrees from from 1970 to 2014 for both men and women is then:
men: 617.6
women: 940.8
Explanation:
from 1970 to 2014 it is 44 years so we plug 44 into x for both equations
Men:
y = 3.9(44) + 446
y = 171.6 + 446
y = 617.6
Women:
y = 14.2(44) + 316
y = 624.8 + 316
y = 940.8
