Answer:
Dot plot or bar graph
Step-by-step explanation:
A dot plot and bar graph would both show the exact amount of cars each day. You didn't give me any options to chose from so if these are not one of your answers, be more specific next time.
Answer:
A line graph.
Explanation (know this, it helps in the future!):
The graph of anything across time (which this is, since we're looking at number of cars for each hour of the day) is almost always going to be a LINE graph.
The x axis is time. The y axis is the thing we're actually measuring (number of cars).
Remember this for the future!
