Let

x ----> the number of months as a member

y ----> the total cost in dollars

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

In this problem we have

The slope is equal to

The y-intercept is equal to

substitute

-4, -2, 1, 4

step-by-step explanation:

domain = x values

range = y values
