To solve the equation \( 13 = \frac{k}{-4} + 9 \), follow these steps:

1. **Isolate the term with \( k \):**
   \[
   13 - 9 = \frac{k}{-4}
   \]
   \[
   4 = \frac{k}{-4}
   \]

2. **Solve for \( k \) by multiplying both sides by \(-4\):**
   \[
   k = 4 \times -4
   \]
   \[
   k = -16
   \]

So, the solution is \( k = -16 \).
