Answer:
The units of the average growth rate is number of accidents per day.
Step-by-step explanation:
We are given the following in the question:
The independent variable is the day of the year.
The function is the cumulative number of accidents since the first of the year at a certain dangerous intersection.
Average growth represents the rate at which the dependent variable changes as the independent variable changes.
Independent variable: day of the year
Dependent variable: cumulative number of accidents
Thus, the growth rate will have units

Thus, the units of the average growth rate is number of accidents per day.
The slope is going from left to right instead of right to lift.(opposite direction)
