The scatter plot below shows the linear trend of the number of golf carts a company sold the month of february and a line of best fit representing this trend.

it is a different question from repairing golf carts read

a. write a function that models the number of golf carts sold as a function of the number of days in the month of february

b. what is the meaning of the slope as a rate of change for this line of best fit.

Part A)

Part B) see the explanation

Step-by-step explanation:

Part A) Write a function that models the number of golf carts sold as a function of the number of days in the month of February

Let

x ----> the number of days

y ----> the number of golf carts sold

we know that

The linear equation in slope intercept form is equal to

where

m is the slope or unit rate

b is the y-intercept or initial value

In this problem

The y-intercept is the point (0,90)

so

Find the slope m

The formula to calculate the slope between two points is equal to

take two points from the graph

(0,90) and (16,0)

substitute the values in the formula

simplify

 ---> is negative because is a decreasing function

therefore

The linear equation is equal to

Part B) What is the meaning of the slope as a rate of change for this line of best fit

The slope is

That means ----> every 8 days 45 less cars are sold

the answer is here: : )
