To find the slope of the line from the graph, we use the formula for slope:

$m = \frac{{y_2 - y_1}}{{x_2 - x_1}}$

This formula uses two points $(x_1, y_1)$ and $(x_2, y_2)$ on the line. From the graph, we can observe the following two points:

1. The first point appears to be $(1, 1)$.
2. The second point is around $(4, -2)$.

Using these coordinates:

$m = \frac{{-2 - 1}}{{4 - 1}} = \frac{{-3}}{{3}} = -1$

So, the slope of the line is -1.

Would you like further clarification or details? Here are five follow-up questions related to this topic:

1. How do we interpret a negative slope in terms of the graph's behavior?
2. What are the steps for finding the slope if the points are not integer values?
3. What is the meaning of a slope of 0 in a graph?
4. How can you identify if two lines are parallel just by looking at their slopes?
5. How does changing the slope affect the steepness of the line?

Tip: The slope of a line tells you how much the line rises or falls for every unit of horizontal movement.
