Answer: B. 95.0
Step-by-step explanation:
In statistics , the famous empirical rule says that " if the data is normally distributed then 68% of the observations will be contained within 
standard deviations from the arithmetic mean, 95% of the observations will be contained within 
standard deviations from the arithmetic mean and 99.7% of the observations will be contained within 
standard deviations from the arithmetic mean".
Hence, B is the correct answer.
2x-3y=6
3y=2x-6
y=2/3x-2
Slope = 2/3
Therefore B
