Solve the problem.Suppose that the speed of a car, measured in miles per hour (mph), is monitored for some short period of time after the driver applies the brakes.

Is the slope of the graph positive or negative and is the slope constant, or does it change over time?
A. Negative, constant B. Negative, changes over time C. Positive, changes over time D. Positive, constant
