Question

http://prntscr.com/h50h4v

1. 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?

@dude

Answer 2

Any more info?

Answer 3

@Aureo YES... what else do you need to answer the questions?

Answer 4

how would you answer first question ??
Q1) label the x and y-axis. We can't tell what the line represents here... (it seems like u need to switch x and y axis values, but hmm can't say for sure)
Q2) pick two points from where the line passes through and use the slope formula ( if you're using excel for graph, excel can provide u the equation)
Q3)context ??? again..no idea what graph represents here
Q4)if you're looking for a value u can find this on excel as well
Q5) need more information
Q6) ^

Answer 5

in short, post the scenario.

Answer 6

I answered question 1 few days ago and i did your whole part 2 of the graph with the of best fit
