The table below represents the distance of a car from its destination as a function of time:

Time
(hour)
x

Distance (miles)
y

0

900

1

850

2

800

3

750

Part A: What is the y-intercept of the function, and what does this tell you about the car? (4 points)

Part B: Calculate the average rate of change of the function represented by the table between x = 1 to x = 3, and tell what the average rate represents.
