The slope of a graph line is determined by calculating the:
change in the horizontal values divided by the change in the vertical values.
change in the horizontal values multiplied by the change in the vertical values.
change in the vertical values divided by the change in the horizontal values.

BC and DE
Many cars are made with an automatic feature called cruise control. When the driver sets a car on cruise control, a computer adjusts the engine to maintain the car’s speed constant. When a car is on cruise control on a straight road, the acceleration of the car is best described as:
equal to the initial speed when the cruise control was set.
equal to zero.
greater than it was before the cruise control was set.
less than it was before the cruise control was set.
A car goes from 30 miles per hour (mph) to 60 mph in six seconds. The acceleration of the car is:

6 mph/s
30 mph/s
180 mph/s
Which point on the speed versus time graph in Figure 4-1 has the highest acceleration?
A
B
C
D
Which of the following statements about the graph in Figure 4-1 is FALSE?
The speed of the car at point D is twice the speed of the car at point A.
The speed of the car is increasing at point B.
The speed of the car is constant at point D.
The speed of the car is increasing at point C.
