Question

What liner regression fits (0,8),(1,6),(1,7),(2,5),(4,1),(5,1),(6,0)

Answer 1

The points provided in the question can be arranged in a tabular format in a graphing calculator as shown below:

A linear regression model is given in the form:

`y=ax+b`

The graph can be drawn using the graphing calculator to model the relationship:

The graphing calculator provides the following information about the relationship:

The parameters are:

`\begin{gathered} a=-1.4 \\ b=7.8 \end{gathered}`

Substituting these parameters into the linear regression model, we have the relationship to be:

`y=-1.4a+7.8`
