Question

Determine the equation of the linear regression line for the data.

Income. Amount

700. 230

1500. 150

1100. 250

1400. 120

1500. 240

Answer 1

y = -0.081779661 x + 229.4067797

I uploaded the spreadsheet for you in the resources section..

The R-coefficient is -0.476893686 which is not good.

The data does not fit the linear model...

the y-values bounce up and down as x increases, unbecoming of a line
