Different hotels in a certain area are randomly selected, and their ratings and prices were obtained online. using technology, with x representing the ratings and y representing price, we find that the regression equation has a slope of 135 and a y-intercept of negative 397. what is the equation of the regression line?

The equation of the regression line is y=135x-397.

Step-by-step explanation:

In a regression line x representing the ratings and y representing price.

The general form of a regression line is

          .... (1)

where, m is slope and b is y-intercept.

It is given that the regression equation has a slope of 135 and a y-intercept of negative 397. It means

Substitute m=135 and b=-397 in equation (1) to find the equation of the regression line.

Therefore the equation of the regression line is y=135x-397.
