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

Quizplus · Accepted Answer

The slope of the line would be negative because it costs more to finish an activity more quickly. This is because shorter durations usually require more resources to complete in a shorter amount of time, which increases the cost. Therefore, as the duration of an activity decreases, the cost will typically increase, resulting in a negative slope.
