r value i.e Correlation between x value and y value = 0.769
=Standard deviation of the x-coordinate = 5.508
=Standard deviation of the y-coordinate = ?=k
Slope of line is given by formula
If slope of line is m, then
m = 
m= 
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.
This expression is correct. It shows the price John pays for the jeans on the left side of the + symbol (30n), and the amount of tax he has to pay on the right side of the symbol (0.08(30n)).
Hope this helps!
