Biologists have noticed that the chirping rate of crickets of certain species is related to temperature, and the relationship appears to be very nearly linear. A cricket produces 113 chirps per minute at 70 degrees Fahrenheit and 173 chirps per minute at 80 degrees Fahrenheit. What is the slope of the graph of a linear equation that models the temperature T as a function of the number of chirps per minute N?

Do this the same way as the last one.

Two points

(N,T)

(113, 70)

(173, 80)

T = m N + b

m = (80-70)/(173-113)
