Answer:

The signup fee is $13

Step-by-step explanation:

we know that

The equation in point slope form is equal to

where

m is the slope or unit rate of the linear equation

(x1,y1) is a ordered pair of the line

Let

x -----> the number of months

y -----> the total cost of a gym membership

In this problem we have

The slope of unit rate is equal to

The ordered pair is

substitute

----> equation in point slope form

Convert to slope intercept form

---> equation in slope intercept form

The y-intercept is the signup fee (value of y when the value of x is equal to zero)

therefore

The signup fee is $13
