The line graphed in the xy-plane below models the total cost, in dollars, for a cab ride, y, in a certain city during nonpeak hours based on the number of miles traveled, x.

The figure presents the graph of a line in the x y plane titled “Total Cost for a Cab Ride.” The x axis is labeled “Distance traveled, in miles,” and the integers 0, 5, and 10 are indied. There are vertical gridlines at each integer from 1 through 10. The y axis is labeled “Cost, in dollars,” and the integers 0, 5, 10, and 15 are indied. There are horizontal gridlines at each integer from 1 through 15. The line begins on the y axis at the point with coordinates 0 comma 3, and slants upward and to the right. It passes through the point with coordinates 5 comma 13.

According to the graph, what is the cost for each additional mile traveled, in dollars, of a cab ride?

A.

$2.60

B.

$3.00

C.

$5.00

D.

$2.00
