Q:

# HELP PLEASE ASAP! BRAINLIESTTTTTT1. Which variable did you plot on the x-axis, and which variable did you plot on the y-axis? Explain why you assigned the variables in that way.2. Write the equation of the line of best fit using the slope-intercept formula y=mx+b. Show all your work, including the points used to determine the slope and how the equation was determined.3. What does the slope of the line represent within the context of your graph? What does the y-intercept represent?4. Test the residuals of two other points to determine how well the line of best fit models the data.5. Use the line of best fit to help you to describe the data correlation.6. 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?7. According to your line of best fit, what is the arm span of a 74-inch-tall person?My plot:68 inches 65 inches68 inches 67 inches64 inches 64 inches36 inches 37 inches61 inches 64 inches69 inches 70 inches65 inches 66 inches70 inches 69 inches62 inches 61 inches71 inches 70 inches64 inches 65 inches70 inches 72 inches

A:
If you talk of a scatter plot, regularly the x-axis is used to plot the explanatory variable, this is the possible cause; while the y-axis is used to plot the varibale that is being explained, the result, the efffect.

If you are dealing with a function or model, you the convention is to use the x-axis for the independent variable, this is the input, while the y-axis is for the output or dependent varibale (which is determined by the independent variable).
