The attached diagram shows the graph depicting a proportional relationship.
How do you identify a graph that represents a proportional relationship?
A graph represents a proportional relationship if it is a straight line that passes through the origin (0,0) and the ratio of y-values to x-values remains constant.
In the graph whose diagram is attached below, it is the only option that shows a straight line that passes through the origin (0, 0).
Therefore, the graph that represents a proportional relationship is given in the attachment below.
