Titik c (x, y) dengan perbandingan AC : CB= 8 : 3
m = 8 dan n = 3
A(-2, 1) B(3, -4)
x = ( (mx2) + (nx1) ) / m + n
x = ( 8(3) + 3(-2) ) / (8 + 3)
x = (24 - 6) / (11)
x = 19/11
y = ( (my2) + (ny1) ) / m + n
y = ( (8(-4) + 3(1) ) / (8 + 3)
y = (-32 + 3) / 11
y = -29/11
maka koordinator titik C adalah (19/11, -29/11)
