Question Analysis
This question tests the ability to determine if a given line is a graph of a direct variation function. The student needs to check if the line passes through the origin and if the ratio of the coordinates is constant.

Key Concept Explanation
A direct variation function has the form , and its graph is a straight line passing through the origin. The constant of variation can be found using the ratio of the y-coordinate to the x-coordinate of any point on the line (except the origin).

Step-by-step Solution
1. Identify the given points: and .
2. Check if the line passes through the origin: it does, since one of the points is
