The correct answer is D. A graph is considered proportional if it is a straight line and the line goes through the origin.

In a proportional relationship, the ratio between the values of the dependent variable (y) and the independent variable (x) remains constant. This constant ratio is represented by the slope of the line.

When a graph is a straight line, it indicates that the relationship between the variables is linear. If the line passes through the origin (0,0), it means that when the independent variable...
