Question

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?

Answer 1

A)

Explanation:

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