Question

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 385. Complete parts​ (a) and​ (b) below. a. What is the equation of the regression​ line? Select the correct choice below and fill in the answer boxes to complete your choice.

Answer 1

`y = 135x+385`

Explanation:

Given that different hotels in a certain area are randomly​ selected, and their ratings and prices were obtained online.

x representing the ratings and y representing​ price

Regression equation slope =135 and y intercept = 385

Hence we can write regression equation as

y = Slope *x + intercept

`y = 135x+385`

For a unit change in x, 135 units of y is changed and when x=0, y =385
