A Rachel must pay $37 per month to use the gym.
B. Rachel must pay $20 per month to use the gym
C. Rachel must pay a $37 membership fee to join the gym.
D. Rachel must pay a $20 membership fee to join the gym.

Respuesta :

" Rachel must pay a $20 membership fee to join the gym " can be interpreted from the y-intercept of the function ⇒ D

Step-by-step explanation:

The form of the linear function is f(x) = mx + b, where

  • m is the slope (rate of change) of the function
  • b is the y-intercept (initial amount) of the function

∵ f(x) = 37 x + 20 models the total cost for Rachel to be a member

   at a gym for x months

∵ f(x) = m x + b

∴ m = 37 and b = 20

∵ m represents the rate of change

- That means she must to pay 37 per month for x months

∴ Rachel must pay $37 per month to use the gym

∵ b represents the initial amount

- That means she pays a fixed amount one time

∴ Rachel must pay a $20 membership fee to join the gym

" Rachel must pay a $20 membership fee to join the gym " can be interpreted from the y-intercept of the function
