tolong di bantu kak pakai caranya thx

Cari persamaan garismasing2 terlbih dahulu
1. (3,0) dan (0,8)
(y-8)/(0-8) = (x-0)/(3-0)
(y-8)/-8 = x/3
y-8 = -8x/3
y = -8x/3 + 8

2. (6,0) dan (0,-3)
(y-(-3))/(0-(-3)) = (x-0)/(6-0)
(y+3)/3 = x/6
y+3 = 3x/6
y = x/2 - 3

Titik potong: samakan persamaan
y1 = y2
-8x/3 + 8 = x/2 - 3
-8x/3 - x/2 = -3 -8
-16x/6 - 3x/6 = -11
-19x/6 = -11
x = 66/19
x = 3 9/19

masukkan x ke salah satu persamaan untuk medapatkan y,
y = x/2 - 3 = (66/19)/2 - 3 = 66/38 - 3 = 33/19 - 57/19 = -24/19 = -1 5/9

Jawaban A {3 9/19; -1 5/9}
