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?

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

The answer is the fourth option "15; it represents the one-time sign-up fee." x represents the number of months you have the gym membership which would mean the 15 would represent the sign up fee. So, you pay 15 dollars for signing up for x months.

Hope this helps!

f(x) is the value of the function. b is the value of the function when x equals zero or the y-coordinate of the point where the line crosses the y-axis in the coordinate plane.
