a 68 degrees F, a cricket chirps 24 times per min. at 40 degrees F, the same cricket chirps 86 times per min.

express the number of chirps (y) as a linear function of the Fahrenheit temperature (x)

express the number of chirps (y) as a linear function of the Fahrenheit temperature (x)

amistre64 · Answer

we have two "coordinates" we can use to find a "slope".

24,68   and  86,40

68-40
------   = slope
24-86

28/-62 = -14/31

better flip that to get y chirps to degrees

y = -31/24x + b

24 = -31/14(68) + b

b = 24 + 31(68)/14

y = -31/14x + 174.57 if I did it right :)
