Final answer:

The rule for y is y = 3x.

Step-by-step explanation:

The given set of points represents a pattern where the y-values increase as the x-values increase. To determine the rule for y, we need to find the relationship between the x-values and the corresponding y-values.

Let's analyze the differences between successive y-values:

1st difference: 3-0 = 3

2nd difference: 12-3 = 9

3rd difference: 27-12 = 15

Each 2nd difference is 3 times the 1st difference.

So, the rule for y is y = 3x
