Question

At work, Brett must check and record the internal temperature of the freezer on an hourly basis. When working properly, the temperature should remain constant over time. What word describes the slope of a line showing the temperature of the freezer as a function of time in hours when the freezer is working properly?

positive
zero
negative
undefined

Answer 1

The correct word to describe the slope of a line showing the temperature of the freezer as a function of time in hours, when the freezer is working properly, is **zero**. This is because the temperature should remain constant over time, resulting in a horizontal line on the graph, which has a slope of zero.
