Answer:
1st answer
Step-by-step explanation:
From pythagorus theorem.
Since hypotenuse

Square root of 15 because you don't know what know is going to go after it, unlike the others where you can guess the numbers that goes after it
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.
