To find out how much is left on the loan after 9 years, we can substitute \( x = 9 \) into the equation of the line of best fit:
\[ y = 15,413 - 1,635x \]
Substituting \( x = 9 \):
\[ y = 15,413 - 1,635(9) \]
Now calculate \( 1,635 \times 9 \):
\[ 1,635 \times 9 = 14,715 \]
Now, substitute this value back into the equation:
\[ y = 15,413 - 14,715 \]
Now perform the subtraction:
\[ y = 698 \]
Therefore, the amount left on the loan after 9 years is $698.
