Question

Quizplus · Accepted Answer

If the slope of line L₁ is negative, then it means the line is sloping downwards from left to right. A line perpendicular to it would be sloping upwards from left to right, which means its slope would be positive. Therefore, the slope of the line perpendicular to L₁ may be positive.
