A scatter plot is made to model the amount of money left to pay on a mortgage. The data used for the scatter plot are shown in the table:

Number of Months 3 5 1 2 0 4
Money Owed $114,000 $100,000 $118,000 $116,000 $120,000 $112,000

What does the y-intercept of the model represent?
The amount of the mortgage that has been paid that month
The monthly payments
The original amount of the mortgage
The number of months it takes to pay off the mortgage
