According to a sleep foundation, in 2011 a certain nation averaged 6.3 hours of sleep each weeknight. In 1918, they averaged about 8 hours and 15 minutes of sleep per weeknight. Model these data by a linear equation, and use it to predict the year when the nation will not be sleeping at all on a weeknight. Model these data by a linear equation, assuming that the initial year is t=0.
