y = (5/3)x - 4/3
m = 5/3
m tegak lurusnya = - 3/5
Persamaan garis melalui (2, - 3) dan m = - 3/5 adalah
y - b = m(x - a)
y + 3 = (- 3/5)(x - 2)
5y + 15 = - 3x + 6
3x + 5y + 9 = 0
3y-5x+4=0 ⇔ 3y=5x-4 ⇔ y = 5/3 x - 4/3
Maka, m1 = 5/3
karena tegak lurus, maka ; m1 x m2 = -1 ⇔ 5/3 x m2 = -1 ⇔ m2 = -3/5
y - y1 = m ( x - x1)
y - (-3)= -3/5 (x - 2)
5(y + 3) = - 3x + 6
5y + 15 +3x - 6 = 0
3x + 5y +9 = 0
CARA PRAKTIS :
3x + 5y =3. 2 - 5. (-3)
3x-5y = -9
3x + 5y + 9 = 0
