Tentukan Persamaan garis melalui titik(-2,6)Dan(4,-3)

(-2,6) => x1 = -2 , y1 = 6
(4,-3) => x2 = 4 , y2 = -3
rumus mencari persamaan garis
y - y1 / y2 - y1 = x - x1 / x2 - x1
y - 6 / -3 - 6 = x - (-2) / 4 - (-2)
y - 6 / 9 = x + 2 / 6
(bagian bawa dibagi 3)
y - 6 / 3 = x + 2 / 2
2(y - 6) = 3(x + 2)
2y - 12 = 3x + 6
2y = 3x + 6 + 12
3x - 2y + 18 = 0
