(-8 , 5) = (x - 4 , y + 5) ------> x - 4 = 8 -----> x = 12
y + 5 = 5 -----> y = 0
jadi X ( 12 , 0)
Y' = (x , y) + (- 4 , 5)
(2 , 7) = (x - 4 , y + 5) -------> x - 4 = 2 ------> x = 6
y + 5 = 7 ------> y = 2
jadi ,Y (6 , 2)
Z' = (x , y) + (- 4 , 5)
(3 , 1) = (x - 4 , y + 5) --------> x - 4 = 3 ------> x = 7
y + 5 = 1 ------> y = - 4
jadi, Z = (7 , - 4)
