To find the slope of the line in the given graph, we can apply the slope formula:

$\text{slope (m)} = \frac{{y_2 - y_1}}{{x_2 - x_1}}$

From the graph, we can identify two clear points on the line:

• Point 1: $(-5, -5)$
• Point 2: $(5, 5)$

Now, using the slope formula:

$m = \frac{{5 - (-5)}}{{5 - (-5)}} = \frac{{5 + 5}}{{5 + 5}} = \frac{10}{10} = 1$

Therefore, the slope of the line is 1.

Here are 5 related questions to explore:

1. How can we determine the y-intercept from this graph?
2. What is the equation of the line in slope-intercept form?
3. How would the graph look if the slope were negative?
4. How do you find the slope if only one point is given?
5. What does a slope of 0 represent on a graph?

Tip: The slope can tell us how steep a line is and in which direction it moves (positive slope means it rises from left to right).
