To analyze the relationships in the given table, let's evaluate each relation based on the characteristics mentioned:
1. **Relation 1**:
- Values of \( x \): 3, 4, 5, 5, 6
- Values of \( y \): 3, 5, 7, 9, 11
- The values of \( x \) increase and the values of \( y \) increase as well, indicating a linear relationship. This relation represents a function because for each \( x \) value, there is a unique \( y \) value (with the exception of the repeated \( x = 5 \)). It shows a constant rate of change (the difference in \( y \) values is consistent).
2. **Relation 2**:
- Values of \( x \): 5, 6, 7, 8, 9
- Values of \( y \): 31, 28, 25, 22, 19
- In this relation, as \( x \) increases, \( y \) decreases in a linear fashion. This is a function, shows a constant rate of change (specifically, a decrease), and is also linear but not increasing.
3. **Relation 3**:
- Values of \( x \): 2, 3, 4, 5, 6
- Values of \( y \): 3, 3, 3, 3, 3
- In this relation, \( y \) remains constant regardless of \( x \). Therefore, this shows a linear relationship (specifically a horizontal line), it represents a function, and exhibits a constant rate of change (zero).
4. **Relation 4**:
- Values of \( x \): 7, 8, 9, 9, 10
- Values of \( y \): 10, 20, 30, 40, 50
- This relation shows an increasing relationship where each increase in \( x \) leads to proportional increases in \( y \) (constant rate of change), reflecting a linear relationship. It represents a function because (despite the repeated \( x = 9 \)) each input maps to a single output when considered across the distinct \( x \) values.
Let’s summarize what we have identified:
- **Relation 1**: Linear, function, constant rate of change, increasing.
- **Relation 2**: Linear, function, constant rate of change, decreasing.
- **Relation 3**: Linear, function, constant rate of change, flat (constant).
- **Relation 4**: Linear, function, constant rate of change, increasing (and proportional).
Now let's review the answer choices in relation to the properties checked:
- **Relation 1**: Correct for a linear relationship, function, increasing, constant rate.
- **Relation 2**: Correct for a linear relationship, function, constant rate, but decreasing and not increasing.
- **Relation 3**: Correct for constant rate (zero), linear, function.
- **Relation 4**: Correct for a linear relationship, function, constant rate, increasing, and also proportional.
Given the question's requirements of identifying which relations fall under specified properties, we conclude:
- **Relation 1** meets the criteria of being increasing, linear, and constant rate of change.
- **Relation 4** also meets criteria for linear, function, proportional.
Thus, the final answer, considering all the criteria stated, would be **relation 1 and 4**.
1. **Relation 1**:
- Values of \( x \): 3, 4, 5, 5, 6
- Values of \( y \): 3, 5, 7, 9, 11

It shows a constant rate of change (the difference in \( y \) values is consistent).
2. **Relation 2**:
- Values of \( x \): 5, 6, 7, 8, 9
- Values of \( y \): 31, 28, 25, 22, 19
- In this relation, as \( x \) increases, \( y \) decreases in a linear fashion. This is a function, shows a constant rate of change (specifically, a decrease), and is also linear but not increasing.
3. **Relation 3**:
- Values of \( x \): 2, 3, 4, 5, 6
- Values of \( y \): 3, 3, 3, 3, 3
- In this relation, \( y \) remains constant regardless of \( x \). Therefore, this shows a linear relationship (specifically a horizontal line), it represents a function, and exhibits a constant rate of change (zero).
4. **Relation 4**:
- Values of \( x \): 7, 8, 9, 9, 10
- Values of \( y \): 10, 20, 30, 40, 50
- This relation shows an increasing relationship where each increase in \( x \) leads to proportional increases in \( y \) (constant rate of change), reflecting a linear relationship. It represents a function because (despite the repeated \( x = 9 \)) each input maps to a single output when considered across the distinct \( x \) values.
Let’s summarize what we have identified:
- **Relation 1**: Linear, function, constant rate of change, increasing.

Based on the analysis of the four relations provided earlier, here are the answers to questions A, B, and C:
### A: Which table(s) do not represent a function?
- **Relation 1** has a repeated \(x\) value (5) leading to multiple \(y\) values (7 and 9), thus it does not satisfy the definition of a function.
- **Relation 2, Relation 3, and Relation 4** each assign a unique \(y\) value to each \(x\) value.
**Answer: Relation 1.**
### B: Which table(s) represent a linear relationship?
- **Relation 1**: Linear (increasing).
- **Relation 2**: Linear (decreasing).
- **Relation 3**: Linear (constant).
- **Relation 4**: Linear (increasing and proportional).
**Answer: Relations 1, 2, 3, and 4 all represent linear relationships.**
### C: Which table(s) show a decreasing relationship?
- **Relation 1**: Increasing (not decreasing).
- **Relation 2**: Decreasing (as \(x\) increases, \(y\) decreases).
- **Relation 3**: Does not show an increasing or decreasing trend (constant).
- **Relation 4**: Increasing (not decreasing).
**Answer: Relation 2.**
### Summary of Answers:
- **A**: Relation 1.

If question B specifies that only one relation can be selected for representing a linear relationship, the best answer would be:
**B: Relation 1.**
This choice is based on the context that typically, if "best" refers to an increasing linear relationship, Relation 1 represents a clear upward trend. However, if the preferred interpretation is simply about linearity without additional qualifiers, any of the relations could fit, but since you require one, Relation 1 is a solid choice due to its increasing nature.
If there are additional criteria specifying which linear relationship is desired (increasing, constant, etc.), please let me know so I can refine the answer further!
