Which statement describes the rate of change of the number of items the worker packed in boxes with respect to the number of minutes the worker has been packing items in boxes?

Answer 1

The rate of change is 4 items per minute.
(Each increase of 1 minute corresponds to 4 more items; e.g., (18−10)/(4−2)=4, (34−18)/(8−4)=4, (66−34)/(16−8)=4.)
