Question

Arnold has recorded the number of chirps per minute ( x) that crickets makeat different temperatures (y).He has determined that the association is linear and that the line of best fit isy = (x + 50What is the interpretation of the slope and y-intercept of this equation?

Answer 1

Given:

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)/(4)x+50`

So, when x = 0, y = 50 which will be the y-intercept

And every increase in x by 1, the value of y will increase by 1/4 which represents the slope of the line

So, the answer will be option C
