The function f(x)=37x+20 models the total cost for Rachel to be a mender at a a gym for x months. What can be interpreted from the y-intercept of the function?

If it costs her [ 37x + 20 ] to be a member of the gym for 'x' months,
that means that it cost her 20 at the beginning just to sign up, before
any time went by, and then another 37 every month after that.
