caption: The image shows a black and white drawing of a graph with a line going through it, which is a representation of the relationship between the two variables. The graph is composed of a series of points connected by a line, with each point representing a different variable. The x-axis of the graph is labeled with the values of the variables, while the y-axis is labeled as the slope of the curve. The text accompanying the graph provides further information about the variables and their relationship.
