Question: A researcher tracked the number of plastic bottles found on a beach and the number of tourists who visited that beach over a 7-day period. The line of best fit relating tourists x to plastic bottles collected y is: y=2x+15. On one particular day, 20 tourists visited the beach, and 70 plastic bottles were collected.

B) The actual number of bottles is 15 fewer than predicted.
C) The actual number of bottles matches the predicted amount.
D) The number of tourists is too low to use the equation for prediction.
