Answer:
a)1.245
Step-by-step explanation:
There is a mistake in the question, the corrected version is:
"the standard deviation of the x-coordinates is 5.768 and the standard deviation of the y-coordinates is 8.112"
The equation of a line, in general terms, is:
y = a + b*x
where b is its slope and a is its y-intercept.
In a regression, the slope can be computed as follows:
b = r * standard deviation of the y-coordinates / standard deviation of the x-coordinates = 0.885*8.112/5.768 = 1.245
