Customers of a phone company can choose between two service plans for long distance calls. The first plan has a $ 29 monthly fee and charges an additional $ 0.14 for each minute of calls. The second plan has a $ 17 monthly fee and charges an additional $ 0.19 for each minute of calls. For how many minutes of calls will the costs of the two plans be equal?

yes because there is exactly one y value for every x value

for function there can't be more than one value for every x value

none.

step-by-step explanation:

m1=5,m2=0

compare the two slopes in the decimal form. if the slopes are equal, then the lines are parallel. if the slopes are not equal, then the lines are not parallel.
