This week, we are covering relationships that can be approximated by linear equations. For instance, y = 453x + 3768 represents the increase in cost of tuition and fees at public four-year universities. Now think about how this might apply in your chosen field and answer the following question: What is an example of a relationship (in your chosen field) that can be represented by a linear equation? Show the equation and explain the relationship. Please provide a reference for your example (website, book, etc.)

See explanation below.

Step-by-step explanation:

We assume that the data is given by :

x: 30, 30, 30, 50, 50, 50, 70,70, 70,90,90,90

y: 38, 43, 29, 32, 26, 33, 19, 27, 23, 14, 19, 21.

Where X represent the cost for scholarships in thousands of dollars and y represent the cost of life for an academic semester (The data comes from the web)

We can find the least-squares line appropriate for this data.  

For this case we need to calculate the slope with the following formula:

Where:

So we can find the sums like this:

With these we can find the sums:

And the slope would be:

Nowe we can find the means for x and y like this:

And we can find the intercept using this:

So the line would be given by:

We have an inverse linear relationship since the slope is negative between the variables of interest.

you can first factor out the n to get n(1+5). we know that 1+5 is 6, so we just have 6n.
