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?
In the given function, C(m) = 11.99m + 7, the coefficient of 'm', which is 11.99, represents the slope.
To find the slope, you need to look at the term multiplied by 'm' in your equation. The coefficient of that term gives you the slope.
In this case, the coefficient of 'm' is 11.99. So, the slope of the function is 11.99.
This means that for every 1 month increase in the subscription time, the total cost of the streaming service increases by $11.99.
