From the graph, we can identify two points on the line. Let's choose the points (-3, 6) and (3, -6).
Step 2: Use the slope formula
The slope \( m \) of a line passing through two points \((x_1, y_1)\) and \((x_2, y_2)\) is given by:
\[ m = \frac{y_2 - y_1}{x_2 - x_1} \]
Step 3: Substitute the coordinates into the formula
Substitute the coordinates of the points (-3, 6) and (3, -6) into the slope formula:
\[ m = \frac{-6 - 6}{3 - (-3)} \]
\[ m = \frac{-12}{3 + 3} \]
\[ m = \frac{-12}{6} \]
