Biologists have noticed that the chirping rate of crickets of a certain species is related to temperature, and the relationship appears to be very nearly nearly linear. A cricket produces 113 chirps per minute at $70^{\circ} \mathrm{F}$ and 173 chirps per minute at $80^{\circ} \mathrm{F} .$
(a) Find a linear equation that models the temperature $T$ as a function of the number of chirps per minute $N .$
(b) What is the slope of the graph? What does it represent?
(c) If the crickets are chirping at 150 chirps per minute, estimate the temperature.
