Answer:
It is
degrees Fahrenheit when the crickets are chirping
times a minute.
Variables
and 
y-intercept 
slope
Step-by-step explanation:
As the chirps are
times per minute for
degrees Fahrenheit we will consider it in
.
Now when the chirps are
times and temperature is
degrees we consider it
.
To find the slope we can use point-slope formula.
Where
is the slope and 
To find y-intercept we will plug out the value of slope in
choosing point
.
So 
And the equation is 
To calculate temperature for
chirpings we have to plug
and
in our above equation which is in form of
degrees Fahrenheit.
Finally we have :
Temperature
degrees Fahrenheit.
With variables
and 
y-intercept
and
slope
