Answer:
$2/mile
Step-by-step explanation:
Look at the graph. We see that two points on this line are (0, 2) and (9, 20).
The "run" is (9 - 0), or 9, and the "rise" is (20 - 2), or 18.
The slope of this yellow line is thus m = rise / run = (18 dollars) / (9 miles) = $2/mile
This slope of the yellow line is the incremental taxi fare per mile traveled and is speed of the car and is m = 2 mph.
