Answer 1

A. To find the equation for the Linear Regression Line, you need to open the Desmos Graphing Calculator using the provided link. Input the data into a table. Then, ask the calculator for a Linear Regression Line. The equation for the Line of Best Fit will be displayed in the calculator.

B. To determine if there is a correlation between the test marks and the homework marks, you can examine the correlation coefficient. If the correlation coefficient is close to 1 or -1, it indicates a strong correlation. If it is close to 0, it indicates a weak correlation.

C. The slope of the Line of Best Fit can be used to make a probabilistic interpretation. For example, if the slope is 0.89, it means that for every 1 point increase in the test mark, the homework mark is expected to increase by 0.89 points on average.
