Question

Tentukan bayangan A(2,3) hasil dilitasi dengan faktor skala 4 pusat dilitasi O(2,4)!??

Answer 1

(x, y) = (2, 3)

k = 4

(a, b) = (2, 4)

x' = k(x - a) + a
   = 4(2 - 2) + 2
   = 8 - 8 + 2
   = 2

y' = k(y - b) + b
   = 4(3 - 4) + 4
   = 12 - 16 + 4
   = 0

A' (x', y') = (2, 0)

Answer 2
