Question

Use the image to answer the question.



A graph with x and y axes shows four curves labeled A, B, C, and D. Curve A has a step-like structure initiating at the origin, increasing steadily, tapering to a point, and again increasing. Curve B begins at the origin and is an increasing concave down curve. Curve C is a straight line with a unit slope. Curve D is a straight line that initiates at a point on the y-axis and then increases steadily.
Identify the proportional relationship from the graph.

Answer 1

The proportional relationship in the context of a graph is typically represented by a straight line through the origin (0,0), indicating a constant ratio between the x and y values. Among the curves described:

- Curve A has a step-like structure and does not represent a constant ratio.
- Curve B is an increasing concave down curve, which also does not represent a constant ratio.
- Curve C is a straight line with a unit slope, which indicates a consistent proportional relationship.
- Curve D is a straight line that starts above the origin, indicating a relationship that does not go through the origin.

Therefore, the correct response indicating the proportional relationship is:

**Graph C**
