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 11.99.
The y-intercept of the function is 7.
We interpret the slope of this function as the rate at which the total cost increases per month subscribed. In this case, for every additional month subscribed, the total cost increases by $11.99.
We interpret the y-intercept of this function as the initial cost or the cost when the number of months subscribed is zero. In this case, the initial cost or the sign-up fee is $7.
