Use the image to answer the question.
An illustration shows a graph labeled Football Cost. The horizontal axis is labeled Quantity and ranges from 0 to 5 in increments of 1. The vertical axis is labeled Cost and ranges from 0 to 39 in increments of 3. An upward slanting line segment connects points plotted at left parenthesis 0 comma 0 right parenthesis, left parenthesis 1 comma 9 right parenthesis, left parenthesis 2 comma 18 right parenthesis, left parenthesis 3 comma 27 right parenthesis, and left parenthesis 4 comma 36 right parenthesis.
The price for footballs is displayed in the graph. Derive the equation of the proportional relationship through the origin.

The equation for the proportional relationship through the origin is given by y = kx, where k is the constant of proportionality.
From the graph, we can see that when the quantity (x) is 1, the cost (y) is 9. We can use this information to find the constant of proportionality (k):
9 = k(1)
Therefore, k = 9.
So, the equation of the proportional relationship is:
y = 9x.

In three to five sentences, describe two impacts of obtaining nonrenewable resources and how these have been affected by increasing population.(4 points)
One impact of obtaining nonrenewable resources is environmental degradation through processes such as mining, drilling, and extraction which can harm ecosystems and contribute to climate change. As the population has increased, there has been a higher demand for these resources, leading to increased levels of degradation. Additionally, the use of nonrenewable resources such as fossil fuels also entail air and water pollution which can negatively affect human health and the environment.
In 2-3 sentences order to expand agriculture and stimulate a sagging economy, the Brazilian government eased environmental laws which allowed large tracts of rainforest to be cut down or burned. In three to five sentences, construct a potential chain of consequences for what can happen as a result of this kind of deforestation. The chain does not have to be linear (i.e., five steps in a row), but can have several branches, one for each different potential consequence. Your chain should include at least four steps, including the original event.(4 points)
As a result of the deforestation in Brazil, the first consequence can be the loss of habitats for animals and indigenous people which can lead to a reduction in biodiversity. The second consequence can be soil degradation as the nutrient-rich layer of the soil is removed during deforestation leading to soil infertility. Thirdly, with the loss of trees, less carbon dioxide is absorbed from the atmosphere which can further exacerbate climate change. Finally, deforestation can contribute to the erosion of riverbanks and the pollution of water bodies, leading to water scarcity and other environmental problems.
In 2 sentences, describe how a person can reduce consumption of natural resources when drinking water. Assume that there is no change in the amount of water consumed and that the change is only in the way water is produced.(4 points)
A person can reduce their consumption of natural resources when drinking water by using a reusable water bottle instead of single-use plastic bottles. Additionally, they can install a water filtration system in their home instead of relying on bottled water which requires fossil fuels and energy to be produced and transported.
