Respuesta :

Using a calculator, the equation of linear regression, which is the line of best-fit for the data, is given by:

y = -465.46x + 17,267.56.

How to find the equation of linear regression using a calculator?

To find the equation, we need to insert the points (x,y) in the calculator.

In this problem, the points are in the format (Month, Principal Balance), hence the points we have to insert in the calculator are given as follows:

(1, 16,791.47), (2, 16,331.80), to (12, 11,671.40).

Inserting these points into the calculator, the equation of linear regression, which is the line of best-fit for the data, is given by:

y = -465.46x + 17,267.56.
