An internet service provider charges 18$ per month plus an initial set up fee. one customer paid a total of $81 after 2 months of service. a. write an equation modeling this situation

Step-by-step explanation:

we know that

The linear equation in slope intercept form is equal to

where

m is the slope or unit rate of the linear equation

b is the y-intercept or initial value of the linear equation

Let

x -----> the number of months

y ----> total charges in dollars

In this problem

The slope or unit rate is equal to

we have the ordered pair (2,81)

substitute in the equation

solve for b

subtract 36 both sides

-----> initial set up fee

therefore

The equation is

where is the image?
