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

$\text{slope} = \frac{\Delta y}{\Delta x} = \frac{y_2 - y_1}{x_2 - x_1}$

Looking at the graph, two points on the line are approximately:

• $(-7, -7)$
• $(7, 7)$

Using these points in the slope formula:

$\text{slope} = \frac{7 - (-7)}{7 - (-7)} = \frac{7 + 7}{7 + 7} = \frac{14}{14} = 1$

So, the slope of the line is 1.

1. How do you find the slope of a vertical or horizontal line?
2. What is the significance of a slope of 0?
3. How does a positive slope compare to a negative slope in terms of direction?
4. Can the slope formula be used for curved lines?
5. How does changing the slope affect the steepness of a line?

Tip: When finding the slope from a graph, choose points that are easy to read and far apart to reduce errors in calculation.
