Tell whether the lines with the given slopes are parallel, perpendicular, or neither. $$m _ { 1 } = 5 , m _ { 2 } = - \frac { 1 } { 4 }$$
A)neither
B)parallel
C)perpendicular

Question

Quizplus · Accepted Answer

Two lines are perpendicular if the product of their slopes is -1. Here, $5 \times -\frac{1}{4} = -\frac{5}{4}$, which is not -1, so the lines are neither parallel nor perpendicular.
