a) A(1,-7) e B(3,-5)
xM=(1+3) / 2 = 4/2 = 2
yM=(-7-5) / 2 = -12/2= -6
M(2,-6)
b)A(-1,5) eB (5,-2)
xM=(5-1)/2 = 4 / 2 = 2
yM=(5-2) /2 = 3/2
M(2, 3/2)
c)A (-4,-2) eB (-2,-4)
xM=(-4-2) / 2 = -6 / 2 = -3
yM=(-4-2) / 2 = -6 / 2 = -3
M=(-3;-3)
xM=(1+3) / 2 = 4/2 = 2
yM=(-7-5) / 2 = -12/2= -6
M(2,-6)
b)A(-1,5) eB (5,-2)
xM=(5-1)/2 = 4 / 2 = 2
yM=(5-2) /2 = 3/2
M(2, 3/2)
c)A (-4,-2) eB (-2,-4)
xM=(-4-2) / 2 = -6 / 2 = -3
yM=(-4-2) / 2 = -6 / 2 = -3
M=(-3;-3)
