Natalie kept a record of the number ,x, of people in front of her when she entered the snack bar line at a movie theater, and the time y, in minutes, until she bought her food. She drew a scatter plot for which the line of best fit is y=2x+1. If there are 15 people in front of her when she enters the snack bar line, about how long should Natalie expect it to take until she buys her food?
