A constant rate means that the value of the rate does not change over time. In this context, it means that the temperature is decreasing at a steady pace without speeding up or slowing down.

Average Rate of Change: The average rate of change measures the total change in a function divided by the total time taken for that change. It's different from a constant rate because it can include periods of acceleration or deceleration.
Linear Function: A linear function has a constant rate of change, meaning its slope remains consistent throughout its domain.
Slope: When analyzing linear functions, slope represents the constant rate at which one variable changes with respect to another variable.
