Answer: A [tex]\dfrac{1}{2}[/tex]
Step-by-step explanation:
From the given picture, it can be seen that green line is perpendicular to the red line.
Since , the product of slope of two perpendicular lines is -1.
Therefore, the product of slope of green line and red line must be -1.
i.e.[tex]\text{Slope of green line}\times-2=-1[/tex]
Divide -2 on both sides, we get
[tex]\text{Slope of green line}=\dfrac{1}{2}[/tex]
