To find the loan amount after 9 years using the given equation of the line of best fit \( y = 15,413 - 1,635x \), we need to substitute \( x = 9 \) into the equation.
\[
y = 15,413 - 1,635(9)
\]
Calculating \( 1,635 \times 9 \):
\[
1,635 \times 9 = 14,715
\]
Now, substitute this back into the equation:
\[
y = 15,413 - 14,715
\]
\[
y = 698
\]
So, the loan amount left after 9 years is \( \text{\$698} \).
\[
y = 15,413 - 1,635(9)
\]
Calculating \( 1,635 \times 9 \):
\[
1,635 \times 9 = 14,715
\]
Now, substitute this back into the equation:
\[
y = 15,413 - 14,715
\]
\[
y = 698
\]
So, the loan amount left after 9 years is \( \text{\$698} \).
