5. The average number of daily domestic flights on wide-body jets was 220 in 2007 and has decreased by 15 flights per year since then. Let n be the average number of daily domestic flights on wide-body jets at t years since 2007. a) Use the description above to complete the table to the right. Year 2007 2008 2012 2019 t n b) Use the table to sketch a graph of a linear model that uses t as the independent variable (input). c) Use what you learned filling in the table to write a linear equation that models this situation. Use t as the independent (input) variable and n as the dependent (output) variable. Hint: What are the slope and y-intercept? d) Use the linear model (your equation) to predict the average number of daily domestic wide-body flights expected in the year 2015.
