titik A(2,1), B(5,1), dan C(3,6) didilatasikan dengan faktor skala 4 dan pusat P(-2,1). Bayangan titik B adalah

A'(x',y') = 4(2,1) + (2-(-2),1-1)
A'(x',y') = (12,4)

B'(x',y') = 4(5,1) + (5-(-2),1-1)
B'(x',y') = (30,4)

C'(x',y') = 4(3,6) + (3-(-2), 6-1)
C'(x'y') = (17,29)

Titik A(x,y) => D[k, (a,b)] => A'(2(x - a) + a, 2(y - b) + b)

B(5, 1) => D[4, (-2, 1)] => B'(2(5 - (-2)) + (-2), 2(1 - 1) + 1) = (12, 1)
