From the description provided, Curve C is a straight line with a unit slope. A straight line with a constant slope indicates a proportional relationship, meaning that as one variable increases, the other variable increases at a constant rate. Since Curve C has a unit slope, it shows a direct and proportional relationship between the x and y values, whereas the other curves (A, B, and D) do not represent a consistent ratio between the x and y values. Therefore, the proportional relationship in the graph is represented by Curve C.
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.
