Linear equations are used to represent relations that have constant rates
The linear regression equation that models the data in this table is
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
The regression equation is represented as:
Where:
and
So, we have:
Also, we have:
Hence, the linear regression equation is:
