The coordinates given in the question are not provided. Without the coordinates it's impossible to graph the line and determine which statement is true.
It is important to have the coordinates to graph the line, and then we can determine if the line is a proportional relationship by looking at the slope of the line, if it is a constant value then it represent a proportional relationship.
The statement A and B are incorrect, as passing through the origin does not determine whether the relationship is proportional or not.
C and D are correct, whether the line passes through the origin or not, it can be determined if it represents a proportional relationship by looking at the slope of the line.
Please provide the coordinates in order to proceed with the question.
