Concept explainers
Americans are getting married later in life, or not getting married at all. In 2010, more than half of Americans ages 25 through 29 were unmarried. The bar graphs show the percentage of never-married men and women in this age group for four selected year. The date are displayed as two sets of four points each, one
In this exercise, you will use the red line for the men shown on the scatter plot to develop a model for the percentage of never-married American males ages 25-29.
a. Use the two points whose coordinates are shown by the voice balloons to find the point-slope from of the equation of the line that models the percentage of never-married American males ages 25-90, y, x years after 1980.
b. Write the equation form part (a) in slope-intercept form. Use function notation.
c. Use the linear function to predict the percentage of never-married American males ages 25-29, in 2020.
