In a proportional relationship, the ratio between the two variables remains constant. In this table, when we divide the y-values by the x-values, we always get the same result. For example, when we divide 2 by 10, we get 0.2. When we divide 3 by 15, we also get 0.2. Similarly, when we divide 8 by 40, we get 0.2 again. Therefore, the ratio between the variables is constant, indicating a proportional relationship.
