Answer the questions in Chapter 2: Section 2.3.
Percentage of the Male Population Never Married
Use the red line for the men shown on the scatter plot to develop a model for the percentage of nevermarried American males ages 25-29.
Question 1
Use the points whose coordinates are shown by the voice balloons to find the point-slope form of the equation of the line that models the percentage of never-married American males ages 25-29, y, x years after 1980. Simplify your equation to slope-intercept form. What is the slope of the line? (Do not round.)

Question 2
Use the points whose coordinates are shown by the voice balloons to find the point-slope form of the equation of the line that models the percentage of never-married American males ages 25-29, y, x years after 1980. Simplify your equation to slope-intercept form. What is the y-intercept? (Do not round.)
Question 3
Use your equation from the previous two problems to predict the percentage of never-married American males, ages 25-29, in 2015. Express your answer with two decimal places.
