To find the equation for the linear regression line, you need to input the data into the Desmos Graphing Calculator and perform the linear regression analysis. Unfortunately, as an AI, I do not have the capability to access or click on external links or inputs. However, you can easily do this by visiting the Desmos Graphing Calculator website or using the mobile app.

To find the equation for the Linear Regression Line using the Desmos Graphing Calculator, you would follow these steps:
1. Open the Graphing Calculator using the provided link.
2. Click on the "Table" button on the calculator's toolbar to open a table.
3. Input the Test Mark(x) data in the first column and the Homework(y) data in the second column of the table.
4. Once you have entered the data, the calculator will automatically plot the points on the graph.
5. To find the Linear Regression Line, click on the spanner/wrench icon in the calculator's toolbar to open the options menu.
6. In the options menu, select the "regression" tab.
7. Under the regression tab, you will see various options for regression lines. Select the "Linear" option, as we are looking for a Linear Regression Line.
8. The calculator will now display the equation for the Linear Regression Line on the graph.
Now, let's answer the questions based on this information:
A. To find the equation for the Linear Regression Line, you would input the equation displayed on the graph into the "Response area." The equation will be in the form of "y = mx + b", where "m" represents the slope and "b" represents the y-intercept.
B. To determine the correlation between the test marks and the homework marks, you would need to calculate the correlation coefficient, typically denoted as "r." Unfortunately, the Desmos Graphing Calculator does not provide the correlation coefficient directly. However, you can manually calculate it using statistical software or spreadsheet programs like Excel. Once you have obtained the correlation coefficient value, you can input your interpretation of the correlation into the "Response area."
C. To make a probabilistic interpretation using the slope of the line of best fit, you would need to apply statistical concepts. Specifically, you can interpret the slope as the rate of change in the dependent variable (in this case, homework marks) for each unit change in the independent variable (test marks). For example, if the slope is 0.5, you can say that, on average, the homework mark increases by 0.5 for every unit increase in the test mark. You can input your specific interpretation into the "Response area."
