If an activity's cost is plotted against its duration on axes with zeros at the origin:
A)The slope of the line is positive because it costs more to finish an activity more quickly.
B)The slope of the line is negative because a shorter activity costs less than a longer one.
C)The slope of the line is negative because it costs more to finish an activity more quickly.
D)The slope of the line is positive because a longer activity costs more than a shorter one.

Question

The slope of the line is negative because it costs more to finish an activity more quickly. This is because shorter durations require more resources and have higher costs per unit of time, such as overtime or expedited shipping fees. Therefore, the cost decreases as the duration increases, resulting in a negative slope.
