Final answer:

The student's question involves understanding a proportional relationship between two variables x and y, as seen in a linear equation format where y is directly proportional to x. A graph of this relationship would display a straight line through the origin, reflecting the constant ratio of y to x.

Step-by-step explanation:

The question is about a proportional relationship between two variables, x and y, as demonstrated by the given table. If a relationship is proportional, then the ratio between y and x remains constant. This means that the relationship can be expressed as y = kx, where k is the constant of proportionality. In the table provided, as x increases, y increases at a consistent rate, which suggests a direct proportionality. When this data is graphed, we expect to see a straight line that goes through the origin (0,0), which is indicative of a direct relationship. This shows the dependence of y on x. If the points in the question (which appear to have been provided in error, as they do not match the initial table) were graphed, and they also formed a straight line through the origin, that would further confirm that y and x are directly proportional to one another. However, if there is a 'b' value in the equation y = b + mx, this means that the line does not pass through the origin, and that the relationship is not direct proportionality. In such cases, m represents the slope, and b represents the y-intercept of the graph showing the linear relationship between x and y, not a proportional relationship.
