Hynes Strength Headquarters charges $40 for a sign-up fee plus $20 per month to join the gym. Orlando has paid $180 for his gym membership so far. What linear equation represents this situation?

40x + 20y = 180
y - 180 = 20(x - 40)
y = 20x + 40
x = 40y + 20
y = 40x + 20
y - 40 = 20(x - 180)

I think that it is y = 20x + 40 but I’m not sure.

Answer 1

Yes, you are correct, the answer is y = 20x + 40. 40 is the y-intercept value and 20 is the slope because that is the fee that must be payed every month, or x amount of times.
