which is a graph of a proportional relationship?
Answer
Explanation:
Step1: Recall proportional - relationship property
A proportional relationship has the form $y = kx$ ($k\neq0$), and its graph is a straight - line passing through the origin $(0,0)$.
Step2: Analyze each graph
Check if the line in each graph passes through the origin. A straight - line that passes through the origin represents a proportional relationship.
Answer:
The graph that is a straight - line passing through the origin is the graph of a proportional relationship. Without seeing the specific details of which graph among the four has this property, in general, look for the straight - line graph that intersects the point $(0,0)$.
