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:
