Answer:

[tex]y = 135x+385[/tex]

Step-by-step 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

[tex]y = 135x+385[/tex]

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