a. x + 2y + 16 = 0 ---> m = -1/2
b. 6y - 9x + 12 = 0 ---> m = 9/6 = 3/2
10. persamaan garis yg menghubungkan titik (-7, 3) dan (14, -6)
(y - 3) / (-6 - 3) = (x + 7) / (14 + 7)
(y - 3) = -9(x + 7) / 21
y = -3/7 x - 3 + 3
y = -3/7 x ---> m = -3/7
y = -3/7 x tegak lurus (1, 2)
garis yang melalui (1, 2) m = 7/3
y - 2 = 7/3(x - 1)
3(y - 2) = 7x - 7
3y - 6 = 7x - 7
0 = 7x - 3y - 1 atau 3y - 7x + 1 = 0
