Points A' and B' are images of points A and B after a 270 degree rotation about the origin. If the slope of ray AB is ​3, what is the slope of ​ray A'B'? Explain.
A. A rotation of 270 degrees would result in a line parallel to ray AB . Since the slopes of parallel lines are opposite​ reciprocals, the slope of ray A'B' is (Blank).
B. A rotation of 270 degrees would result in a line perpendicular to ray AB. Since the slopes of perpendicular lines are opposite​ reciprocals, the slope of ray A'B' is (Blank).
C. A rotation of 270 degrees would result in a line parallel to ray AB . Since the slopes of parallel lines are​ equal, the slope of ray A'B' is (Blank).
D. A rotation of 270 degrees would result in a line perpendicular to ray AB . Since the slopes of perpendicular lines are​ equal, the slope of ray A'B' is (Blank).
