Answer:
Variability
Step-by-step explanation:
Variability in simple terms may be described as differences in measurement or reading of a certain construct or phenomenon. Variability measures include range, standard deviation or variance. In most cases, variation or degree of Variability is measured about a central value called the mean. This is because same measurement about a certain phenomenon or study would usually not yield the same result value. Hence, the mean is used to record the average of these measurement and the differences in each measurement from the mean is also recorded, this is called the standard deviation which is a Variability measure.
Thus VARIABILITY means successive observation of a phenomenon do not yield exactly the same result.

The slope of the line is -1
the equation would be y = -1x
Steps to solve:
-12x - 2(x + 9) = 5(x + 4)
~Distribute
-12x - 2x - 18 = 5x + 20
~Combine like terms
-14x - 18 = 5x + 20
~Add 18 to both sides
-14x = 5x + 38
~Subtract 5x to both sides
-19x = 38
~Divide -19 to both sides
x = -2 (Option B)
Best of Luck!
