Predict the gas mileage for a car that weighs 3,400 pounds. (3.4 thousand pounds)
Question 11
11.
Find the zero of the function.
Question 12
12.
Describe the correlation in your graph.
Positive correlation
Negative correlation
Relatively no correlation
What does that mean in this situation?
When the car is zero pounds, it can go 6.24 mph.
When the weight is that number of pounds, the car is too heavy to move.
