A ( - 3 , 2 ) mean :
xA = - 3
yA = 2
B ( 3 , - 2 ) mean :
xB = 3
yB = 2
x- coordinate of midpoint :
xmid = ( xB + xA ) / 2
xmid = ( - 3 + 3 ) / 2 = 0
y- coordinate of midpoint :
ymid = ( yB + yA ) / 2
ymid = ( - 2 + 2 ) / 2 = 0
Coordinates of the midpoint : ( 0 , 0 )
AB = sqrt [ ( xB - xA ) ^ 2 + ( yB - yA ) ^ 2 ]
AB = sqrt [ ( 3 - ( - 3 ) ) ^ 2 + ( - 2 - 2 ) ^ 2 ]
AB = sqrt [ ( 3 + 3) ) ^ 2 + ( - 2 - 2 ) ^ 2 ]
AB = sqrt [ 6 ^ 2 + ( - 4 ) ^ 2 ]
AB = sqrt ( 36 + 16 )
AB = sqrt ( 52 )
AB = 7.2111
AB = 7.2
to the nearest tenth
