b) Use the slope you calculated and a point provided and do the following:
With a slope m and a point :
When you simplify it, it should be in the form of:
c) The y-intercept is the percentage of non-married women for the year 1970 (x = 0).
d) If 1970 = 0, then 2010 = 40. Solve the equation in b with x = 40.
e) For this one, set the equation equal to 100, find the x-value and add it to 1970.
