Step 1:I'll solve this step by step using the proportional relationship test.
Step 2:: Recall the definition of a proportional relationship
This means $$\frac{b}{a}$$ should be the same for all pairs of values.
A proportional relationship exists when the ratio between corresponding values remains constant.
Step 3:: Calculate the ratio \frac{b}{a} for each table
- Third row: $$\frac{16}{12} = 1.33$$ (Not consistent)
Table 1: Table 2: Table 3: Table 4:
Final Answer
Table 2 shows a proportional relationship between a and b.
