In the xy-plane, line k passes through the point (1,1) and line m passes through the point (1,-1). Are lines k and m perpendicular to each other?
1)Lines k and m intersect at the point (1,-1)
2)Line k intersects the x-axis at the point (1,0).
OA is E...can sum1 pls post a detailed explanation of the same??
