A curve extends linearly through (0 point 5, 6) through (2, 6) rises diagonally through (6, 14), and rises through (7, 18) and (8, 20) on the x y coordinate plane. A. The cost of the delivery truck between 1 mile and 2 miles is constant. B. The cost of the delivery truck between 1 mile and 2 miles is decreasing. C. The cost of the delivery truck between 1 mile and 2 miles is increasing. D. The cost of the delivery truck between 1 mile and 2 miles cannot be determined from the given information
