Biologist have found The number of shirts 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°F. When they charge 172 times a minute it is about 80°F

Step-by-step explanation:
Let y be the number of chirp and x be the temperature.
Given:
When crickets chirp 124 times a minute = 68°F
When crickets chirp 172 times a minute = 80°F
Solution:
Standard linear equation is written as:
Where:
y = Number of chirps
m = Temperature
From the above statement, crickets chirp 124 times a minute it is about 68°F. When they chirp 172 times a minute it is about 80°F
So, the equation is written as:
----------(1)
----------(2)
Substitute equation 1 from equation 2.
x = 4
Now, substitute x = 4 in equation 1 for value of b.
b = -148
Now we substitute x = 4 and b = -148 in equation 1.
Therefore, the relation between cricket chirp and its temperature is given by below equation.
