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 m, which is 11.99.
The y-intercept of the function is 7.
The slope of this function represents the rate of change of the total cost with respect to the number of months subscribed to the service. In other words, for every additional month subscribed to the service, the total cost increases by $11.99.
The y-intercept of this function represents the initial cost or the fixed cost of signing up for the service. In this case, it is $7, which means that even if the subscriber doesn't subscribe to any months, they still need to pay a one-time sign-up fee of $7.
