Persamaan garis yang melalui titik (2,-3) dan (5,4) adalah A.7x + 3y - 23 = 0 B.7x + 3y + 23 = 0 C.7x - 3y + 23 = 0 D.7x - 3y - 23 = 0 Beserta caranya ya Terima

(2,-3) = x1,y1
(5,4) = x2,y2

rumus =

y - y1 / y2 - y1 = x - x1 / x2 - x1
y + 3 / 4 + 3 = x - 2 / 5 - 2
y + 3 / 7 = x - 2 / 3

dikali silang.

3y + 9 = 7x - 14
7x + 3y = -14 -9
7x + 3y - 23 = 0
