Mika wrote the table of points below. xy023568Which explains whether or not Mika has described a proportional relationship, and why?

The table gives the points (0, 2), (3, 5), and (6, 8). Each time x increases by 3, y increases by 3, so the points lie on a line. But when x = 0, y = 2, so the line does not pass through the origin; therefore, the relationship is not proportional. Choice B correctly describes this.
