Entomologists have discovered that a linear relationship exists between the number of chirps of crickets of a certain species and the air temperature. When the temperature is 90° F, the crickets chirp at the rate of 200 times/minute, and when the temperature is 110° F, they chirp at the rate of 300 times/minute. Find an equation giving the relationship between the air temperature T and the number of chirps/minute N of the crickets.
