To determine which table demonstrates a proportional relationship, we need to check if the ratio \( \frac{y}{x} \) remains constant for each pair of \( (x, y) \).
Let's analyze both tables provided.
Table 1:
x | y
10 | 2
15 | 3
40 | 8
Now, we calculate the ratios \( \frac{y}{x} \):
- For \( (10, 2) \): \( \frac{2}{10} = 0.2 \)
- For \( (15, 3) \): \( \frac{3}{15} = 0.2 \)
- For \( (40, 8) \): \( \frac{8}{40} = 0.2 \)
The ratio \( \frac{y}{x} \) is constant (0.2) for all pairs, so this table demonstrates a proportional relationship.
Table 2:
x | y
8 | 2
12 | 3
40 | 4
Now, we calculate the ratios \( \frac{y}{x} \):
- For \( (8, 2) \): \( \frac{2}{8} = 0.25 \)
- For \( (12, 3) \): \( \frac{3}{12} = 0.25 \)
- For \( (40, 4) \): \( \frac{4}{40} = 0.1 \)
The ratio is not constant (0.25 for the first two pairs and 0.1 for the last), so this table does not demonstrate a proportional relationship.
Conclusion: The first table demonstrates a proportional relationship.
