(t + 1 , 16t + 1) = (t + 1 , + 35 + 1)
16t + 1 = + 36
16t - = 36 - 1
16t - = 35 -------> kalikan dengan 2
32t - 25t = 70
7t = 70
t = 10
jadi tranlasi (t , 16t) <==> (10 ,160)
A (1 , 1) ---- T (10 ,160) ------> T' (11 , 161)
2) pada pencerminan terhadap garis x = h ,berlaku x' = 2h - x
(0, 1) --- R : h = 1 ---> x' = 2 ---- R ; h = 3 ----> x' = 4 --- R ; h = 5 ---> x' = 6
membentuk deret aritmatika : 2 , 4 , 6 .......2012
Un = a + (n - 1).b
2012 = 2 + (n - 1) .2
2012 = 2 + 2n - 2
2012 = 2n
n = 1006
jadi bayangan (2012 , 1) diperoleh pada pencerminan yang ke 1006
