Adrian records the number of chirps per minute ( x ) that crickets make at different temperatures ( y ).He determines that the association is linear and that the line of best fit is 𝑦=15𝑥+50y= 51​ x+50.What is the interpretation of the slope and y-intercept of this equation?Click here for long descriptionA.The slope predicts a temperature increase of about 1° for every increase of 50 chirps per minute. The y-intercept shows that when the crickets are not chirping (x = 0), the temperature is 1551​ °.B.The slope predicts a temperature increase of about 1551​ ° 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°.C.The slope predicts a temperature increase of about 50° for every increase of 1 chirp per minute. The y-intercept shows that when the crickets are not chirping (x = 0), the temperature is 0°.D.The chirping increases as the temperature goes down.

A researcher studied the relationship between the number of times a certain species of cricket will chirp in one minute and the temperature outside. Her data is expressed in the scatter plot and line of best fit below. Based on the line of best fit, what temperature would it most likely be outside if this same species of cricket were measured to chirp 140 times in one minute?56637077849198105112119126133485052545658606264666870

A biologist created the following graph to show the relationship between the temperature of water (x), in degrees Celsius, and the number of insect larvae (y) in the water:What does the y-intercept of the graph represent? There were 400 larvae at 0 degree Celsius. There were no larvae at 400 degrees Celsius. The original number of larvae in the water was 400. The original temperature of the water was 400 degrees Celsius.
