1. A new refrigerator starts with a temperature of 21°C. The manual says that once the refrigerator is turned on, it will cool at a rate of 2°C every minute until it reaches its lowest
temperature.
Which of these equations shows the temperature inside the refrigerator as a function of the
number of minutes after it was turned on, r?

Find the slope of the line that contains the following points. r(-2, 4), s(6, -2)

Which graph has a rate of change of zero
