Arnold has recorded the number of chirps per minute (x) that crickets make at different temperatures (y) . He has determined that the association is linear and that the line of best fit is y = 1/4x + 50.

What is the interpretation of the slope and y-intercept of this equation?

A) The slope predicts a temperature increase of about 4 degrees for every increase of 50 chirps per minute. The y-intercept shows that when the crickets are not chirping
(x = 0), the temperature is 1/4 degrees.

B) The chirping increases as the temperature goes down.

C) The slope tells us that for every increase of 1 chirp per minute, we predict that the temperature increases by 40 degrees. The y-intercept tells us that when the crickets are not chirping ( when x = 0 ), the temperature is 0 degrees.

D) The slope predicts a temperature increase of about 1/4 degrees for every increase of 1 chirp per minute. The y-intercept shows that when the crickets are not chirping
(x = 0), the temperature is 50 degrees.
