Desmos Graphing Calculator: Use the link to access the Graphing Calculator. Open a table and input the data. Ask the calculator for a Linear Regression Line (Line of Best Fit)
(3 points)
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
The option "The test mark decreases 0.7 pts for every 1 pt on the homework mark." (8 of 11) has been selected. Press tab to choose a response area, and spacebar to insert it. Press escape to cancel.
A. The equation for the Linear Regression Line is y = mx + b, where m is the slope and b is the y-intercept.
B. There is a strong positive 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: For every 1 point increase in the homework mark, the test mark is expected to increase by 0.7 points.
