To determine which figure shows a set of perpendicular lines, let’s analyze each option:

Options Analysis

A. Both lines are descending and do not meet.

Perpendicularity: Perpendicular lines must intersect at a point. Since these lines do not intersect, they cannot be perpendicular.

 

B. One line is descending (negative slope), and the other is ascending (positive slope), and they intersect at a right angle.

Perpendicularity: This figure shows that the two lines intersect at a 90-degree angle, which means they are perpendicular.
