Answer:

D. 1/2

Step-by-step explanation:

Given:

- Lines a and b are perpendicular.

-  The slope of line a is -2.

What is the slope of line b?

If lines a and b are perpendicular, their slopes are negative reciprocals of each other.

Line B slope is [tex]\frac{1}{2}[/tex].

So, the answer is D.1/2.

Answer:

[tex]\frac{1}{2}[/tex]

Step-by-step explanation:

The slope of the perpendicular line will be the negative reciprocals of the line a so it will be [tex]\frac{1}{-(-2)}[/tex] or [tex]\frac{1}{2}[/tex]

I hope this helps
