3.) Suppose that in the year 2010, the cost of a compact car averaged $14,500 and that in 2013, the cost averaged $16,900. Assuming that the relationship between year x and cost y is linear, develop a formula for predicting the average cost of a compact car in the future.
Let the variable x be the years since 2010. Be sure to use the lower case variables x and y: Formula a.) _______________________.
What do you predict the average cost of a compact car will be in the year 2019? Formula b.)
