I need help making a digital graph I don't know how...I also need help answering these questions
What does the slope of the line represent within the context of your graph? What does the y-intercept represent?

Test the residuals of two other points to determine how well the line of best fit models the data.
Use the line of best fit to help you to describe the data correlation.

Using the line of best fit that you found in Part Three, Question 2, approximate how tall is a person whose arm span is 66 inches?
Thank you so much if you can help!
