To determine the slope of the line in the graph:

1. Identify two points on the line: From the image, two clear points are $(-4, 4)$ and $(4, -4)$.

2. Use the slope formula:
   $m = \frac{y_2 - y_1}{x_2 - x_1}$
   Substituting the coordinates $(x_1, y_1) = (-4, 4)$ and $(x_2, y_2) = (4, -4)$:
   $m = \frac{-4 - 4}{4 - (-4)} = \frac{-8}{4 + 4} = \frac{-8}{8} = -1$

3. Conclusion: The slope of the line is $m = -1$.

Here are five related questions to deepen understanding:

1. What is the slope of a vertical line?
2. How does the slope of a horizontal line compare to that of a diagonal line?
3. If the slope of a line is $0$, what does the graph look like?
4. How does changing the sign of the slope affect the direction of the line?
5. What does a slope of $1$ represent on a graph?

Tip: Always simplify your slope fraction to its lowest terms to ensure accuracy.
