Let’s check out your problem:

The scatterplot shows the temperatures, $y$, in degrees Celsius ($\text{C}^\circ$), of a cup of coffee cooling in a $22^\circ\text{C}$ room at $5$ minute intervals. If $x$ represents the time, in minutes, since the coffee had a temperature of $92^\circ\text{C}$, which of the following could be used to predict the temperature of the coffee for $0 \leq x \leq 60$?
