Biologists have noticed that the chirping of crickets of a certain species is related to temperature, and the relationship appears to be very nearly linear. A cricket produces 112 chirps per minute at 68 degrees Fahrenheit and 175 chirps per minute at 80 degrees Fahrenheit. a) Find a linear equation that models the temperature ?Tas a function of the number of chirps per minute ? b) If the crickets are chirping at 158 chirps per minute, estimate the temperature:
