The monthly cost \( c \) of Marge's phone plan is given by the equation \( c = 40 + m \), where \( m \) is the number of extra minutes she uses in that month.

Name the slope and y-intercept in this situation, and explain what each represents.

Asked by mackjune18

Answer (2)

The slope of the phone plan is 1, representing the increase in cost per extra minute used. The y-intercept is 40, representing the fixed cost of the phone plan. ;

The slope of Marge's phone plan is 1, indicating a $1 increase in cost for each extra minute used. The y-intercept is 40, representing the fixed monthly cost of the plan without any extra minutes. This illustrates a clear linear relationship between the number of extra minutes used and the total monthly cost.
