Diketahui koordinat titik P (-8, 12) Dilatqsi [P, 1/4] memetakan titik (-4, 8) ke titik....

a dan x jarak a20× 15

p(-8, 12) ; D[P, 1/4] ; (-4, 8)
a = -8
b = 12
k = 1/4
x = -4
y = 8
[tex] \binom{x^{i} }{y^{i}} = \binom{k \: \: 0}{0 \: \: k} \binom{x - a}{y - b} + \binom{a}{b} \\ = \binom{ \frac{1}{4} \: \: 0}{0 \: \: \frac{1}{4} } \binom{ - 4 \: \: - ( - 8)}{8 \: \: - 12} + \binom{ - 8}{12} \\ = \binom{ \frac{1}{4} \: \: 0 }{0 \: \: \frac{1}{4} } \binom{4}{ - 4} + \binom{ - 8}{12} \\ = \binom{1}{ - 1} + \binom{ - 8}{12} \\ = \binom{ - 7}{11} [/tex]
jadi, (x', y') =(-7, 11)

semoga membantu:)
