If you alter the "c" value, then you are <u>moving the graph up</u> <em>(or down if c is negative)</em>.
Since you are shifting the graph up, the y-intercept ("h" in your graph) will move up.
Since you are shifting the graph up, then the maximum will shift up.
Since you are shifting the graph up, then the x-intercept ("t" in your graph) will increase (move to the right).

Answer:
46 minutes
Step-by-step explanation:
Sorry about not answering your question sooner, but here is your answer:
In order to get the answer, we have to subtract the original amount of money on the phone card by the amount left ver after the call:
15 - 6.72 = 8.28
Then, we divide this number by 0.18:
8.28 / 0.18 = 46
So, Tammy's call lasted 46 minutes
Hope this helps :)
