Determine whether the lines are parallel,perpendicular,or neither. ?
L1: y = $\frac { 1 } { 2 }$ x - 4
L2: y = - $\frac { 1 } { 2 }$ x - 2

B)Perpendicular
C)Neither

Question

Quizplus · Accepted Answer

The slopes of the lines are $\frac{1}{2}$ and $-\frac{1}{2}$. For lines to be parallel, their slopes must be equal. For lines to be perpendicular, the product of their slopes must be -1. Here, the product is $-\frac{1}{4}$, so the lines are neither parallel nor perpendicular.
