Explanation Definition used: The slope of the line passing through the points ( x 1 , y 1 ) and ( x 2 , y 2 ) is m = y 2 − y 1 x 2 − x 1 , where x 2 ≠ x 1 . Recall: Two lines are perpendicular if and only if the product of their slopes is −1, or if one is vertical and the other horizontal.” Proof: Obtain the slope of the diagonal joining the points ( 4 , 5 ) and ( − 2 , − 1 ) . Substitute ( x 1 , y 1 ) = ( 4 , 5 ) and ( x 2 , y 2 ) = ( − 2 , − 1 ) in m = y 2 − y 1 x 2 − x 1 , m = − 1 − 5 − 2 − 4 = − 6 − 6 = 1 Thus, the slope of the diagonal joining the points ( 4 , 5 ) and ( − 2 , − 1 ) is 1. Obtain the slope of the diagonal joining the points ( − 2 , 5 ) and ( 4 , − 1 )
