Question

Titik X (–3,4) dilatasikan dengan faktor skala 4 dan pusat (1,1). Koordinat titik bayangan adalah

Answer 1

Verified answer

X(-3, 4) D[(1, 1) , 4] X' (x', y')

x' - p = (x - p) k
x' - 1 = (-3 - 1) 4
x' - 1 = (-4) 4
x' - 1 = -16
x' = -16 + 1
x' = -15

y' - q = (y - q) k
y' - 1 = (4 - 1) 4
y' - 1 = (3) × (4)
y' = 12 + 1
y' = 13

koordinator titik bayanganya (-15, 13)
