Question

Diketahui koordinat titik K = (1, 2) dan L = (7, -4). Jika KH * HL = 2 : 1, koordinat titik H adalah...

Answer 1

Jawab: H (5,-2)

Penjelasan dengan langkah-langkah:

KH : HL = 2 : 1

KH = 2 HL

(h -k) = 2 ( l -h)

h - k = 2l -2h

3h = 2l +k

= 2(7,-4) + (1,2)

= (14,-8) + (1,2)

= (15,-6)

h = (5,-2)
