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?

1 answer

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)
