Question

a cell phone company charges $10 per month plus a $25 activation fee. what does the y - intercept represent in context of this function? a the y - intercept is the $25 monthly fee. b the y - intercept is the $25 activation fee. c the y - intercept is the $10 monthly fee. d the y - intercept is the $10 activation fee.

Explanation:

In a linear - cost function for the phone service, the y - intercept is the value of the cost when the number of months (the independent variable) is 0. Since the activation fee is paid once at the start (when the number of months is 0), and the monthly fee is a recurring cost, the y - intercept represents the activation fee. Here, the activation fee is $25.

Answer:

B. The y - intercept is the $25 activation fee.
