The limit problem from the image is:

\[
\lim_{{x \to -8}} \frac{\sqrt{1 - x} - 3}{8 + x}
\]

### Solution:

1. **Direct Substitution**:
   Let's substitute \( x = -8 \) directly into the function:

   \[
   \frac{\sqrt{1 - (-8)} - 3}{8 + (-8)} = \frac{\sqrt{1 + 8} - 3}{0} = \frac{\sqrt{9} - 3}{0} = \frac{3 - 3}{0} = \frac{0}{0}
   \]

   This results in an indeterminate form \( \frac{0}{0} \). Therefore, we need to simplify the expression.

2. **Rationalizing the Numerator**:
   To simplify the expression, we multiply both the numerator and denominator by the conjugate of the numerator, \( \sqrt{1 - x} + 3 \):

   \[
   \frac{\sqrt{1 - x} - 3}{8 + x} \cdot \frac{\sqrt{1 - x} + 3}{\sqrt{1 - x} + 3} = \frac{(\sqrt{1 - x})^2 - 3^2}{(8 + x)(\sqrt{1 - x} + 3)}
   \]

   Simplifying the numerator using the difference of squares:

   \[
   = \frac{(1 - x) - 9}{(8 + x)(\sqrt{1 - x} + 3)} = \frac{-x - 8}{(8 + x)(\sqrt{1 - x} + 3)}
   \]

   Notice that \( -x - 8 = -(x + 8) \), so the expression becomes:

   \[
   \frac{-(x + 8)}{(x + 8)(\sqrt{1 - x} + 3)}
   \]

   Now, cancel the \( (x + 8) \) terms:

   \[
   = \frac{-1}{\sqrt{1 - x} + 3}
   \]

3. **Substitute \( x = -8 \)**:
   Now substitute \( x = -8 \) into the simplified expression:

   \[
   = \frac{-1}{\sqrt{1 - (-8)} + 3} = \frac{-1}{\sqrt{9} + 3} = \frac{-1}{3 + 3} = \frac{-1}{6}
   \]

Thus, the limit is:

\[
\lim_{{x \to -8}} \frac{\sqrt{1 - x} - 3}{8 + x} = \frac{-1}{6}
\]
