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.

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

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

y=−9/2x+10

step-by-step explanation:

let's solve for y.

0−9x−2y=−20

step 1: add 9x to both sides.

−9x−2y+9x=−20+9x

−2y=9x−20

step 2: divide both sides by -2.

−2y

−2

=

9x−20

−2

y=

−9

x+10

proofs involving isosceles triangles often require special consideration because an isosceles triangle has several distinct properties that do not apply to normal triangles.(more about triangle types) therefore, when you are trying to prove that two triangles are congruent, and one or both triangles, are isosceles you have a few theorems that you can use to make your life easier.

step-by-step explanation:

an isosceles triangle has two congruent sides and two congruent angles. the congruent angles are called the base angles and the other angle is known as the vertex angle. ∠bac and ∠bca are the base angles of the triangle picture on the left. the vertex angle is ∠abc
