as well as reserving the body's energy, It insulates the body's heat, which is especially useful in colder climates.
Linear equations are used to represent relations that have constant rates
The linear regression equation that models the data in this table is 
<h3>Regression equation using a graphing calculator</h3>
To calculate the regression equation, we make use of a graphing calculator.
Using the graphing calculator, we have the following data:
- Sum of X = 28
- Sum of Y = 70
- Mean X = 3.5
- Mean Y = 8.75
- Sum of squares (SSX) = 42
- Sum of products (SP) = 101
<h3 /><h3>Formulating the regression equation</h3>
The regression equation is represented as:

Where:
and 
So, we have:


Also, we have:



Hence, the linear regression equation is:

Answer:
Light colored peppered moths decreases in number and dark colored peppered moths increases.
Explanation:
The population of light colored peppered moths decreases whereas the dark colored peppered moths increases in number because the light colored peppered moths are visible to the predator birds whereas the dark colored peppered moths are not visible due to dark coating of the trees so they are saved from the birds and therefore, increase in population of dark colored peppered moths occurs and decrease occur in light colored peppered moths population.
