The cost of a monthly cell phone plan, in dollars, is modeled by the function C(x)= 0.6x + 30, where x is the number of text messages. What does the slope of this line represent?
this has been confusing me for a bit and the assignment is due tonight
The slope of this line is 0.6, and this represents the cost per text message sent. For example, if you send 1 text message, you’ll pay a total of $30.60.
