r value i.e Correlation between x value and y value = 0.769
[tex]A_{x}[/tex]=Standard deviation of the x-coordinate = 5.508
[tex]A_{y}[/tex]=Standard deviation of the y-coordinate = ?=k
Slope of line is given by formula
If slope of line is m, then
m = [tex]r\times \frac{ A_{x}}{A _{y}}[/tex]
m= [tex]0.769 \times \frac{k}{5.508}[/tex]
Substitute the value of k, i.e Standard deviation of the y-coordinate and then you can get the slope of line to three decimal places.
