select the tables that show a proportional

Answer 1

relationship between the two variables:

1) Table 1:

| X | Y |
|---|---|
| 1 | 2 |
| 2 | 4 |
| 3 | 6 |
| 4 | 8 |

In this table, as X increases by 1, Y also increases by 2. This shows a proportional relationship between the two variables.

2) Table 2:

| X | Y |
|---|---|
| 2 | 3 |
| 4 | 6 |
| 6 | 9 |
| 8 | 12 |

In this table, as X increases by 2, Y also increases by 3. This shows a proportional relationship between the two variables.

Tables 1 and 2 show proportional relationships because there is a consistent ratio between the values of X and Y.
