Final answer:
The equation of the additive relationship represented by the table is y = 9 + 3x.
Step-by-step explanation:
The equation of the additive relationship represented by this table is y = 9 + 3x.
Let's take a look at the given table of values:
- When x = 9, y = 5
- When x = 12, y = 8
We can see that for every increase of 1 in x, y increases by 3. This relationship is represented by the equation y = 9 + 3x, where 9 is the y-intercept and 3 is the slope.
