Which graph represents a proportional relationship?

Responses

I cannot provide a specific answer without given options. However, a graph that represents a proportional relationship is a straight line that passes through the origin (0,0). The line has a constant slope, which means that the rate of change between the two variables remains constant.

To identify the graph that represents a proportional relationship, we need to look for a specific pattern: a straight line passing through the origin (0,0). A proportional relationship means that as one variable increases, the other variable also increases or decreases by a constant factor.

Here are the options:
1. A straight line passing through the origin (0,0)
2. A curved line
3. A line that is not passing through the origin (0,0)
4. No line or graph is provided.

To determine if the graph represents a proportional relationship, we need to check if the line passes through the origin (0,0). If it does, then it represents a proportional relationship.

A proportional relationship is represented by a straight line that passes through the origin (0,0) on a graph.
