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?

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

Answer 1

The y-intercept can be found be letting x=0.

Answer 2

ok

Answer 3

I notice you just close the question. Does mean you got this?

Answer 4

no, no one was helping so there was no point LOL

Answer 5

Ok. So you do need help?
If so have you found the y-intercept yet? If so what is it?

Answer 6

isnt it 15, cuz the x intercept is 10x which represents months?

Answer 7

the x-intercept isn't 10x

Answer 8

oh is it 10?

Answer 9

The x-intercept can be found by replacing y with 0 and solving for x.
Where as....
The y-intercept can be found by replacing x with 0 and finding y.

Answer 10

ok.......

Answer 11

You have y=10x+15
to find the y-intercept replace the x with 0 as I have suggested
when x is 0 what do you find y to be...

Answer 12

also the question doesn't ask us to find the x-intercept
just the y-intercept

Answer 13

ok

Answer 14

y =0,15

Answer 15

the y intercept is (0,15)
that is right... when x=0 we have y=15
so some say the y-intercept is 15
if x represents the number of months what do you think the y-intercept means in this case
remember the y-intercept is when you have 0 months (this is what x is when we are lying on the y-axis)
