Answer

neither

Work Step by Step

m=$\frac{y_2-y_1}{x_2-x_1}$ m=$\frac{-12-(-4}{-4-0}$ m=$\frac{-8}{-4}$ m=2 m=$\frac{y_2-y_1}{x_2-x_1}$ m=$\frac{-5-(-4)}{0-2}$ m=$\frac{-1}{-2}$ m=$\frac{1}{2}$ 2$\ne$$\frac{1}{2}$ 2$\times$$\frac{1}{2}$$\ne$-1 Therefore these lines are neither parallel nor perpendicular.
