The graph models a linear relationship between the number of monthly payments made on a loan and the remaining balance in dollars left to pay on the loan.

Which statement describes the x-intercept of the graph?

• The x-intercept is 60, which represents the initial balance in dollars of the loan

• The x-intercept is 27,000, which represents the initial balance in dollars of the loan

• The x-intercept is 60, which represents the number of monthly payments needed to repay the loan

• The x-intercept is 27,000, which represents the number of monthly payments needed to repay the loan
