To complete the statements, we first need to find the missing y-value in the table for \( x = -1 \) using the equation \( y = 2 - 4x \).
1. **Calculate y when x = -1**:
\[
y = 2 - 4(-1) = 2 + 4 = 6
\]
Now, we can fill in the information needed for the statements.
- The x-values are the **inputs**.
- The y-values are the **outputs**.
- The missing value in the table for \( x = -1 \) is \( y = 6 \).
Therefore, the completed statements are:
- The x-values are the **inputs**.
- The y-values are the **outputs**.
- The missing value in the table for x = –1 is y = **6**.

The following are negative impacts on land resources caused by human activity:
1. **Erosion increase due to road construction** - This is a direct result of human activities that disturb the soil and vegetation.
2. **Chemicals used in mining entering the soil** - This human activity can lead to soil contamination and degradation.
3. **Desertification caused by deforestation** - Deforestation, a human activity, removes trees that help retain soil moisture and prevent erosion.
The statements **erosion increase due to ocean waves** and **desertification caused by drought** are generally natural processes rather than direct results of human activity (though human activities can exacerbate them, they are not caused by human actions).
So, the checked items indicating negative impacts due to human activity are:
- Erosion increase due to road construction
- Chemicals used in mining entering the soil
- Desertification caused by deforestation

Humans can have a positive impact on air quality by **using public transportation instead of driving a car**. This action reduces the number of vehicles on the road, leading to lower emissions of pollutants and, consequently, better air quality.
The other two options do not contribute positively to air quality:
- **By moving to a large city, where air quality is better**: This is generally not true, as larger cities often have poorer air quality due to higher traffic and industrial activity.
- **By removing vegetation such as trees and shrubs**: This negatively impacts air quality, as plants help filter pollutants and produce oxygen.
In summary, the positive option is:
- **By using public transportation instead of driving a car**.

Which of the following images is an example of point source pollution?
Water with trash in it.
Dirty foam and water at a shoreline.
Dirty water being emptied into a river through pipes.

The example of point source pollution is **"Dirty water being emptied into a river through pipes."**
Point source pollution refers to contamination that comes from a single, identifiable source, such as a pipe or a drain. In this case, the dirty water entering the river through pipes is a clear, specific source of pollution.
The other two options, "Water with trash in it" and "Dirty foam and water at a shoreline," represent non-point source pollution, as they indicate pollution that comes from multiple, diffuse sources rather than a single identifiable point.

Answered by

The social implications of an environmental policy can vary based on the specific policy and its effects. From the options provided, the following can be considered social implications:
1. **Loss of jobs** - Environmental policies can sometimes lead to job loss in certain industries (e.g., fossil fuels) as they transition to more sustainable practices.
2. **Higher taxes** - Implementing some environmental policies may result in increased taxes or fees to fund environmental protection measures.
3. **Elimination of tourist activities** - Certain environmental protections may restrict activities that are popular with tourists, potentially impacting local economies reliant on tourism.
**Poorer air quality**, **less erosion**, and **cleaner water waste** are not social implications but rather environmental outcomes or conditions resulting from environmental policies.
So, the checked items indicating social implications are:
- **Loss of jobs**
- **Higher taxes**
- **Elimination of tourist activities**
