To determine the slope of a line on a graph, you typically need the coordinates of two points on that line. The slope (m) is calculated using the formula:
\[ m = \frac{y_2 - y_1}{x_2 - x_1} \]
If you can provide the coordinates of two points from the graph, I can help you calculate the slope. Alternatively, if you describe the graph or key points, I can assist you further!
