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 C10; 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
Accepted Solution
A:
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
