Given:
Required:
We need to find the proportional relationship in the given graph.
Step-by-step explanation:
Recall that If the graph of a relationship is a line or a ray through the origin, then it is proportional. If it is a line or ray that does not pass through the origin, then it is not proportional
The blue line in the graph passes through the origin.
The other two lines are not passing through the origin (0,0).
The blue line represents the proportional relationships.
There are only one proportional relationship shown in the coordinate plane below
Final answer:
