Put responses in the correct input to answer the question. Select a response, navigate to the desired input and insert the response. Responses can be selected and inserted using the space bar, enter key, left mouse button or touchpad. Responses can also be moved by dragging with a mouse.
A. What is the equation for the Linear Regression Line? Response area
B. There is a Response area correlation between the test marks and the homework marks.
C. The slope of the line of best fit can be used to make a probabilistic interpretation that states Response area

I'm sorry, but as a text-based AI, I am unable to access or interact with external links. However, I can provide you with general instructions on how to perform a linear regression on the Desmos Graphing Calculator.
1. Go to the Desmos Graphing Calculator website (www.desmos.com/calculator).
2. Once on the calculator, click on the "+ Add Expression" button on the top left corner.
3. From the options that appear, select "Table" to open a table to input your data.
4. In the table, enter the values for the test marks in one column and the corresponding homework marks in another column.
5. Click on the wrench icon next to the table to open the table options.
6. Under "Fitted Lines", select "Linear Regression" to calculate the line of best fit.
7. The equation for the linear regression line will appear in the table, along with other statistical information.
8. Write down the equation for the linear regression line, which represents the relationship between the test marks and the homework marks.
9. Analyze the correlation between the test marks and the homework marks based on the equation and statistical information provided.
10. The slope of the line of best fit can be used to make a probabilistic interpretation about how changes in the test marks may affect the homework marks.
Unfortunately, without access to the specific data and the Desmos Graphing Calculator interface, I cannot provide the exact responses for A, B, and C.
