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
