Biologists have found that the number of chirps some crickets make per minute is related to temperature. the relationship is very close to being linear. when crickets chirp 124 times a minute, it is about 68 degrees fahrenheit. when they chirp 172 times a minute, it is about 80 degrees fahrenheit.

identify the variables

y-intercept=
slope=

create an equation in y=mx+b form

how warm is it when the crickets are chirping 150 times a minute?

, i have to turn this in tomorrow
