Suppose the linear regression line y = 4.009x – 77.531 predicts a pizza parlor's profits based on the number of pizzas sold. If x represents the number of pizzas sold, and y represents the pizza parlor's profits in dollars, about how much can the pizza parlor expect in profits if it sells 325 pizzas?
The answer is B. If x is the number of pizzas sold, and the parlor sold 325 pizzas, then you simply plug in 325 for x. So, you multiply 4.009 by 325 and then subtract your answer by 77.531. Hope I helped!
