Question

Which statement best explains if the graph correctly represents the proportional relationship y = 3.5x?
A graph of a coordinate plane is shown. Points are graphed at 1 comma 3.5 and 2 comma 7. The points are joined by a line.

No, the points shown on the line would not be part of y = 3.5x
No, proportions cannot be represented on a graph
Yes, the points shown on the line would be part of y = 3.5x
Yes, all proportions can be shown on the graph of this line
