Jawaban dan Penjelasan

Berikut ini adalah pilihan jawaban terbaik dari pertanyaan diatas.

diketahui :

Titik P( 2, 3 ) didilatasi dengan faktor skala = 3 dan titik pusat ( 5, 1 )

ditanya :

Titik P setelah didilatasi adalah?

dijawab :

a(x.y) \frac{ \: \: \: \: \: \: \: (p.k) \: \: \: \: \: \: \: }{} a'(x'.y')

x' = k ( x - a ) + a

y' = k ( y - b ) + b

p(2.3) \frac{ \: \: \: \: \: \: \: \: }{ \: \: \: \: \: \: \: \: \: \: \: \: } p'( - 7.9)

x'

= 3 ( 2 - 5 ) + 2

= 3 × ( -3) + 2

= ( -9) + 2

= -7

=============

y'

= 3 ( 3 - 1 ) + 3

= 3 × 2 + 3

= 6 + 3

= 9

kesimpulan :

jadi hasilnya adalah P' ( -7 , 9 )
