Putting it Together: Graph Linear Equations and Inequalities
Joan's uncle Devon is a semiprofessional blogger who writes about media (he would really like to be a paid film critic, but no one has offered yet). Recently, Devon posted a short blog piece complaining about the number of ads on TV these days compared to when he was younger. He was not very scientific about it, and a couple of his readers disputed a claim he made and tried to start an argument. Devon asks Joan, who is taking an algebra class at night, to help him gather and cite some data to support his claim that there are "way more" TV ads now than when he was a kid. Together, they get online and do a little research and find a website that reports some interesting data on the number of minutes of TV commercials per hour since 2009. The data is shown below.Years Since 2009 | Minutes |
