Suppose a snowytree cricket chirps 180 times per minute if the temperature is 102 degrees, and chirps 120 times per minute when the temperature is 90 degrees. Construct a mathematical model that will predict the number of chirps per minute at a temperature in degrees Fahrenheit. (Write your answer as a function in terms of degrees Fahrenheit, expressing it in slopeintercept form.)

bobpursley,
This is hardly calculus
y=mx+b
180=m102+b
120=m90+b
subtrract
60=12m solve for m, then b.
