Quadrilateral WXYZ is on a coordinate plane. Segment XY is on the line x â’ 3y = â’12, and segment WZ is on the x â’ 3y = â’6. Which statement proves how segments XY and WZ are related? They have opposite reciprocals slopes of one third and â’3 and are, therefore, perpendicular. They have the same slope of negative one third and are, therefore, parallel. They have opposite reciprocals slopes of negative one third and 3 and are, therefore, perpendicular. They have the same slope of one third and are, therefore, parallel.
