We are given a table with values for $x$ and $y$. We need to determine if the relationship between $x$ and $y$ is proportional. The table contains the following pairs: $(8, 11.1)$, $(9, 11.2)$, and $(10, 11.3)$.

1. Problem Description

We are given a table with values for xx and yy. We need to determine if the relationship between xx and yy is proportional. The table contains the following pairs: (8,11.1)(8, 11.1), (9,11.2)(9, 11.2), and (10,11.3)(10, 11.3).

2. Solution Steps

A proportional relationship exists if y=kxy = kx for some constant kk. This means that the ratio y/xy/x must be the same for all pairs of xx and yy. Let's calculate the ratio y/xy/x for each pair.
For the first pair (8,11.1)(8, 11.1):
y/x=11.1/8=1.3875y/x = 11.1/8 = 1.3875
For the second pair (9,11.2)(9, 11.2):
y/x=11.2/91.2444y/x = 11.2/9 \approx 1.2444
For the third pair (10,11.3)(10, 11.3):
y/x=11.3/10=1.13y/x = 11.3/10 = 1.13
Since the ratios y/xy/x are not the same for all pairs, the relationship is not proportional.

3. Final Answer

Non-Proportional
