Y = -5x + 12 since the slope of that line is -5x and in order to pass through that point the y intercept must be 12
The temperature would be (21.5 + 6.25) which is 27.75
No it does not stay the same
Original ratio is 6:5 which means it will only stay the same if the amount of movies to band is taken at multiples of this ratio. per sample if 24 movies are sold then
24/6=4 so you will have to multiply or sell 5*4=20 of the band ones to be able to keep same ratio.
