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: 25 of the chicks will be black
Explanation: Since the chickens are intermediate in colour, that is they are not black, they are heterozygous. Let B represent the allele for black colour and B represent the allele for blue colour, therefore the genotype of a chicken with an intermediate colour is Bb. A cross between two Bb chicken will produce 1 BB, 2 Bb and 1 bb chicks. 1 BB will manifest outwardly as black, 2Bb will manifest outwardly as intermediate colored while 1 bb will manifest outwardly as blue colored chicks.
Since one out of four chicks are black colored, if the two chicken produced 100 chicks, the number of chicks that will be black is 1/4 x 100 = 25. Therefore, 25 chicks out of 100 will be black.
