Mrs. Brown had an extra credit problem on the board that read if one line contained points (1,4) (3,7) and another line contained points (3,3) (5,6). Would these lines be parallel, perpendicular, or neither? What answer should the students choose?
If you moved both points from the first line over 2 and down 1 you would get the second line. Because your moving both points the same way they would never intersect.
