39. Biologist have observed that the chirping rate of crickets is related to temperature and the
relationship appears to be linear. A cricket produces 120 chirps per minute at 70°F and 168
chirps per minute at 80°F.
a) Find the linear relationship that relates the temperature y and the number of chirps per
minute x.
b) If the crickets are chirping at 150 chirps per minute estimate the temperature.
c) If the temperature is 95°F, how chirps per minute would the crickets produce?
