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? undefined negative zero positive

Explanation:

Step1: Recall the slope formula

The slope formula is \(m=\frac{y_2 - y_1}{x_2 - x_1}\). Here, \(y\) represents temperature (constant) and \(x\) represents time.

Step2: Substitute values into the formula

Let \(y_1=y_2 = c\) (constant temperature). Then \(m=\frac{c - c}{x_2 - x_1}=\frac{0}{x_2 - x_1}=0\)

Answer:

zero
