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

Number of Months 3 5 1 2 0 4

Money Owed $1,400 $1,000 $1,800 $1,600 $2,000 $1,200

What does the y-intercept of the model represent?

The amount of the balance that has been paid that month

The monthly payments

The number of months it takes to pay off the credit card

The original balance on the credit card

Option D: The original balance on the credit card.

Explanation:

Let x represents the number of months.

Let y represents the money owned.

The y-intercept of a model can be determined when x = 0.

In other words, the y-intercept is the value of y when x = 0.

Thus, from the data, it is obvious that when x = 0, the value of y is $2000.

Thus, the y-intercept is $2000.

Thus, the y-intercept represents the original balance on the credit card.

Hence, Option d is the correct answer.
