An online streaming service charges a monthly fee as well as a one-time sign-up fee. The cost for this online streaming service is modeled by the following function where m represents the number of months the service is subscribed to and C(m) represents the total cost given that amount of time:
C(m) = 11.99m + 7
In the above function, what is the slope?
What is the y-intercept?
How do we interpret the slope of this function?
How do we interpret the y-intercept of this function?
The slope of the function is the coefficient of the m term, which is 11.99 in this case.
The y-intercept of the function is the constant term, which is 7 in this case.
The slope of this function represents the rate at which the cost increases per month. In this case, for every additional month of subscription, the cost increases by $11.99.
The y-intercept of this function represents the initial cost or the fixed cost associated with signing up for the online streaming service. In this case, it costs $7 to sign up for the service.
