Answer:
The answer to your question is the letter B. 2
Step-by-step explanation:
Slope measures the steepness of a line or hill.
In the equation of a line, the slope is the coefficient of the letter x.
If two lines are parallels they have the same slope. If two lines are perpendicular, their slopes are reciprocal.
For this problem, the original slope is -1/2 but for the perpendicular line
slope = 2.
