Q
The outside temperature can be estimated based on how fast crickets chirp.
At 104 chirps per minute, the temperature is 63 °F.
At 176 chirps per minute, the temperature is 81 °F.
Using this information, you can make a formula that relates chirp rate to temperature. Assume the relationship is linear, that is
the points form a straight line when plotted on a graph.
What is the temperature if you hear 128 chirps per minute?
°F
What is the temperature if you hear 72 chirps per minute?
°F

Hint: The X-axis and Y-axis on the graph are not labeled intentionally. You need to substitute the variables from each scenario for the horizontal and vertical axis. For example, in the first scenario, X-axis should be labeled “ ice-cream" and Y-axis should be labeled "The temperature".
