Entomologists have discovered that a linear relationship exists between the rate of chirping of crickets of a certain species and the air temperature. when the temperature is 60°f, the crickets chirp at the rate of 21 chirps/min, and when the temperature is 90°f, they chirp at the rate of 111 chirps/min. (a) find an equation giving the relationship between the air temperature x and the number of chirps per min y of the crickets. y = incorrect: your answer is incorrect. (b) use this function to determine the rate at which the crickets chirp when the temperature is 104°f. incorrect: your answer is incorrect. chirps/min
