Linear equations are used to represent relations that have constant rates

The linear regression equation that models the data in this table is \^y = 2.40476x + 0.33333

<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:

\^y = b\^x + a

Where:

b = \frac{SP}{SSX} and a = MY - bMX

So, we have:

b = \frac{101}{42}

b = 2.40476

Also, we have:

a = MY - bMX

a= 8.75 - 2.4\times 3.5

a= 0.33333

Hence, the linear regression equation is:

\^y = 2.40476x + 0.33333
