cari gradiennya di kumpul besok

ax+by = c ---> gradiennya/m = -a/b
3x-y = 6
m = -3/-1 = 3

3y-1/2x = 3
-1/2x+3y = 3
m = -(-1/2)/3 = (1/2)/3 = 1/2 x 1/3 = 1/6

[tex] \frac{2x-1}{2}= \frac{y-3}{3} \\ 6x-3=2y-6 \\ 6x-2y=-6+3 \\ 6x-2y=-3[/tex]
m = -6/-2 = 3

gradien jk diket melalui titik (x1,y1) dan (x2,y2)\
m = (y1-y2)/(x1-x2)

mel (-1,4) dan (2,1)
m = (4-1)/(-1-2) = 3/-3 = -1

mel (-2,-3) dan (1,-2)
m = (-3-(-2))/(-2-1) = -1/-3 = 1/3

semoga membantu ya.. ^_^
