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.
Answer:
X=-1
Step-by-step explanation:
(X-5)1/2+5=2
(X-5)1/2=2-5
(X-5)1/2=-3
(X-5)=-3 *2
X-5=-6
X=-1
