I'm unable to see the graph you're referring to. However, I can help you understand how to determine the slope of a line if you can provide me with the coordinates of two points on that line or describe the graph. The slope (m) is calculated using the formula:
\[ m = \frac{y_2 - y_1}{x_2 - x_1} \]
Where (x1, y1) and (x2, y2) are the coordinates of two points on the line. Let me know how you'd like to proceed!
