Answer: class B
Explanation:
Normal distributions are bell-shaped and symmetric about the mean. So, if the data is scattered around a lot, like in Class A & B, it would not be normal.
M = -2
In perpendicular lines, the slopes are opposite reciprocal. This means you flip the sign (from + to - or from - to +) and flip the numerator and denominator.
So 1/2 becomes negative, and 2/1 = 2
So the slope is -2
