A biology student is investigating the claim that the temperature can be predicted by counting cricket chirps. He has collected data and comes up with the linear model  T=39.2+0.233r, where T is the temperature in degrees Fahrenheit and r is the number of chirps per minute. Interpret the slope of the equation.     The model predicts a decrease of 0.233 degrees for each increase of 1 chirp per minute. The model predicts a decrease of 39.2 degrees for each increase of 1 chirp per minute. The model predicts an increase of 39.2 degrees for each increase of 1 chirp per minute. The model predicts an increase of 0.233 degrees for each increase of 1 chirp per minute.
