To answer your questions based on the graph with the four dots provided:
1. **What is the y-intercept?**
From the points given, the y-intercept is the value of y when x = 0. In this case, Dot 3 (0, 2) indicates that the y-intercept is **2**.
2. **What is the slope?**
The slope \( m \) can be calculated using any two points from the graph, typically using the formula:
\[
m = \frac{y_2 - y_1}{x_2 - x_1}
\]
Let's take Dot 3 (0, 2) and Dot 4 (2, 3):
\[
m = \frac{3 - 2}{2 - 0} = \frac{1}{2}
\]
Therefore, the slope is **1/2**.
3. **What is the equation of the line in slope-intercept form?**
The slope-intercept form of the equation of a line is given by:
\[
y = mx + b
\]
where \( m \) is the slope and \( b \) is the y-intercept. Substituting in the values:
\[
y = \frac{1}{2}x + 2
\]
Thus, the equation of the line is **y = (1/2)x + 2**.
4. **This is a Response area relationship.**
The relationship here indicates how the points are connected on a linear graph, with the slope showing the rate of change and the y-intercept indicating where the line crosses the y-axis.
You can fill in the response areas with the collected answers:
- Y-intercept: **2**
- Slope: **1/2**
- Equation of the line in slope-intercept form: **y = (1/2)x + 2**

The relationship represented by the points provided is a **linear relationship**. This is indicated by the fact that the points can be connected by a straight line, which means that there is a constant rate of change (the slope) between the variables. In summary:
- **Type of relationship**: **Linear relationship**
This means that for every unit increase in the x-coordinate, the y-coordinate increases by a constant amount (in this case, \( \frac{1}{2} \) per unit increase in x).
- **Type of relationship**: **Linear relationship**
This means that for every unit increase in the x-coordinate, the y-coordinate increases by a constant amount (in this case, \( \frac{1}{2} \) per unit increase in x).

Based on the options provided, the most appropriate choice for the relationship described by the points is:
- **Non-proportional**
Here’s the reasoning:
- **Proportional**: A proportional relationship would pass through the origin (0,0), which is not the case here since the line intersects the y-axis at (0, 2).
- **Non-proportional**: This term indicates that the relationship does not pass through the origin, which fits our points where the line crosses the y-axis at (0, 2).
- **Decreasing**: The relationship is not decreasing since the points show an increase in y as x increases.
- **Non-linear**: The relationship is linear (not non-linear) since it can be represented by a straight line.
So the correct choice from your options is **non-proportional**.
