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

$m = \frac{{\text{{change in y}}}}{{\text{{change in x}}}} = \frac{{y_2 - y_1}}{{x_2 - x_1}}$

By observing the graph, we can choose two points that the line passes through clearly:

1. The line passes through the point $(-8, -4)$.
2. The line passes through the point $(4, 2)$.

Now, we will calculate the slope using these two points:

$m = \frac{{2 - (-4)}}{{4 - (-8)}} = \frac{{2 + 4}}{{4 + 8}} = \frac{6}{12} = \frac{1}{2}$

Thus, the slope of the line is $\frac{1}{2}$.

Would you like more details on this, or do you have any questions?

Here are 5 related questions for further exploration:

1. What is the significance of a positive slope compared to a negative slope?
2. How would the graph change if the slope were $\frac{3}{2}$?
3. Can you identify any other points on the line and confirm the slope calculation?
4. What would the equation of this line be in slope-intercept form?
5. How would you find the slope if the line were vertical or horizontal?

Tip: When identifying points on a line for calculating slope, it's best to use points where the line crosses exactly through the grid lines for more accuracy.
