To determine the slope of a line on a graph, you need to look at how much the line rises (the change in the y-values) over how much it runs (the change in the x-values) between two points on the line. The formula for slope (m) is:
\[ m = \frac{\text{change in } y}{\text{change in } x} \]
If you provide the coordinates of two points on the line or describe the graph, I can help you calculate the slope.
