For each call, a certain phone company charges a connecting fee, and then a cost per minute after that. how much does each call's connecting fee cost?
a.$0.02
b.$0.15
c.$0.18
d.$0.03

The answer is option C.$0.18. The line rises from 18 means it is the initial cost point.

Step-by-step explanation:

We can see that when x = 0, y = 18

This means at 0 minutes or when the call just connects, it is charged 18 pennies or cent.

So, each call's connecting fee cost is $0.18. The line rises from 18 means it is the initial cost point.
