On a coordinate plane, lines G H and G prime H prime are shown. Line G H has points (negative 2, 4) and (4, negative 5). Line G prime H prime has points (4, 2) and (negative 5, negative 4). Are lines GH and G'H' perpendicular? Why or why not?
Yes, they intersect at one point.
Yes, their slopes are negative reciprocals.
