Question

Select the tables that show a proportional relationship.

Proportion Table 1
х у
2/4
3 /6
9 /18
Proportion Table 2
х у
1/5
2/10
4 /20
A. Proportion Table 1
B. Proportion Table 2

Answer 1

B. Proportion Table 2

Proportion Table 2 shows a proportional relationship because when you multiply the first number (x) by a constant factor (in this case, 5), you get the second number (y). For example, 1 * 5 = 5, 2 * 5 = 10, and 4 * 5 = 20. This demonstrates a consistent proportionality between x and y. In Proportion Table 1, this relationship is not consistent, so it does not represent a proportional relationship.
