Question

Which table shows a proportional relationship between x and y?

Answer 1

Answer:

Table 3

Step-by-step explanation:

In a proportional relationship there must be a constant rate of change.

The first table:

6-5 / 9-7 = 1/2

5-3 / 7-4 = 2/3

These are not equal so it is not proportional.

The second table:

10-8 / 150-120 =2/30

8-5 / 120-75 = 3/45

These are not equal so it is not proportional

The third table:

10-8 / 12-10 =2/2 = 1

8-6 / 10-8 =2/2 = 1

These are equal so this table is proportional.
