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.

From the description provided, Curve C, which is a straight line with a unit slope, represents a proportional relationship. In a proportional relationship, as one variable increases, the other variable increases at a constant rate, which is depicted by a straight line passing through the origin. Therefore, the correct response is:
Graph C
