Percentage of young adults using social networking sites. In 2006, the percentage of 18 to 29 year olds who used social networking sites was 49%. In 2013, that percentage had risen to 89%. ( Source: pewresearch.org. ) a. Use the year as the x -coordinate and the percentage as they-coordinate. Find the equation of the line that contains the data points. b. Use the equation in part (a) to estimate the percentage of young adults using social networking sites in 2014. c. Use the equation m part (a) to estimate the year in which the percentage of young adults using social networking sites will reach 100% d. Explain why a linear equation cannot be used for years after the year found m part (c).
