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 a graph is typically represented by a straight line passing through the origin with a constant slope. In the description provided, Curve C is described as a straight line with a unit slope, which indicates that it represents a proportional relationship. Therefore, the correct response is:

Graph C
