1. Using Expedia, the prices for a one-way flight from Chicago to various other cities were recorded. The following table gives the distances from Chicago to 14 selected cities, along with airfare to each of these cities. Use Python to graph the data and find the least squares line. Then use the equation to determine the marginal cost and predict the cost of a flight to a city that is 1500 miles from Chicago.
