1. Bio logists have noticed that the chirping rate of crickets of a certain
species is related to temperature, and the relationship appears to be very
nearly linear. A cricket produces 113 chrips per minute at 70o F and 173 chirps
per minute at 80o F.
(a) Find a linear equation that models the temperature T as a function of the
number of chirps per minutes N.
(b) What is the slope of the graph ? What does it represent?
(c) If the crickets are chirping at 105 chirps per minute, estimate the
