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
