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?
○ a the amount of the balance that has been paid that month
○ b the monthly payments
○ c the number of months it takes to pay off the credit card
○ d the original balance on the credit card

Explanation:

In a linear model for this context, the x-variable is the number of months, and the y-variable is the money owed. The y-intercept occurs when $x=0$, which is the starting point (0 months of payments made). This corresponds to the initial amount owed on the credit card before any payments are made.

Answer:

d. The original balance on the credit card
