Question

Jamal owns a parking garage and is trying to find the relationship between hour of the day and number of cars in the garage. He finds that between 4 am and 10 am he can model this with a linear relationship. The equation for this model is y = 3.56x + 2. About how many cars are entering the garage every hour? A. 1 B. 2 C. 3 D. 4

Answer 1

The number of cars in the garage at 4 am is the y-intercept so 2 cars were there at that time.

Explanation:

Answer 2

The model represented by y = 3.56x + 2 can be interpreted thus.
There were 2 cars in the garage at 4 am (at the beginning of counting) and 3.56 ≈ 4 cars enters the garage every hour.

Therefore, about 4 cars enter the car every hour.
