In order to identify the constant of proportionality from a graph, you would need to look at the slope of the line.
If the graph represents a direct variation, the constant of proportionality would be the slope of the line. In this case, the constant of proportionality would be equal to the change in the y-values divided by the change in the x-values (rise over run).
If the graph represents an inverse variation, the constant of proportionality would be the reciprocal of the slope of the line. In this case, the constant of proportionality would be equal to 1 divided by the slope of the line.
Therefore, to identify the constant of proportionality, you would need to determine the slope of the line from the graph.
