50 Points for Correct answer!!
Quadrilateral WXYZ is on a coordinate plane.
Segment XY is on the line x - y = -3, and segment WZ is on the line x - y = 1. Which statement proves how segments XY and WZ are related?
A: They have slopes that are opposite reciprocals of 1 and -1 and are, therefore, perpendicular.
B: They have the same slope of 1 and are, therefore, parallel.
C: They have slopes that are opposite reciprocals of 0 and undefined and are, therefore, perpendicular.
D: They have the same slope of -1 and are, therefore, parallel.
x-y = -3 => y = x+3...........(1) => slope = coefficient of x = 1
x-y = 1 => y = x-1 ..............(2) => slope = coefficient of x = 1
Therefore the correct statement is
They have the same slope of 1 and are, therefore, parallel.
