Answer:
[tex]y=kx[/tex]
Step-by-step explanation:
The question in English is
The monthly cost in a gym, and, is proportional to the number of times the client visits the gym, what equation represents the relationship between the monthly payment and the number of visits?
we know that
A relationship between two variables, x, and y, represent a proportional variation if it can be expressed in the form [tex]k=\frac{y}{x}[/tex] or [tex]y=kx[/tex]
k represent the constant of proportionality or slope of the linear equation
In this problem
Let
x ----> the number of times the client visits the gym in a month
y ---> the monthly cost in a gym
therefore
[tex]y=kx[/tex]
