Question

The price of a gym membership has a one-time sign-up fee and a monthly fee. The price can be modeled by the function y = 10x + 15, where x is the number of months. What is the y-intercept, and what does it represent?

It's not C

10; it represents the monthly fee
10; it represents the one-time sign-up fee
15; it represents the monthly fee
15; it represents the one-time sign-up fee

Answer 1

Answer: D) 15 it represents the one time sign up fee

Step-by-step explanation:the y intercept is 15 since its not c its d

Answer 2

For this case we have the following equation:
y = 10x + 15
The intersection with the y axis occurs when x = 0.
Evaluating we have:
y = 10 (0) + 15
y = 0 + 15
y = 15
The intersection with the y axis is 15 and represents the inscription in the gym.
Answer:
15; it represents the one-time sign-up fee
