If our model’s any good, once we’ve estimated b 0 and b 1, we can use the following formula to estimate temperature just by counting cricket chirps: Temperature = b 0 + (b 1 )( # of chirps) + 0 Note: our model assumes that “y” and “x” have a linear relationship --- i.e., our model is the equation of a line with intercept b 0 and slope b 1.
