Which line has a slope of -1/2?
Line A
Line B
Line C
Line D

Answer:
Line D
Step-by-step explanation:
Two points that passes through line D : (0,-2) & ( -4 , 0)
[tex]Slope =\dfrac{y_{2}-y_{1}}{x_{2}-x_{1}}\\\\\\=\dfrac{0-[-2]}{-4-0}\\\\\\=\dfrac{0+2}{-4}\\\\\\=\dfrac{2}{-4}\\\\\\=\dfrac{-1}{2}[/tex]
