1.hitunglah gradiem garis AB,CD,EF,GH,dan IJ (ada Digambar) 2.hitunglah gradien garis yang melalui titik2 berikut. a.A(1,3) dan B(0,0) b.C(-8,-1) dan D(-3,-4) c.P(3,-7) dan Q(-4,2) 3.tentukan gradien dari persamaan garis sebagai berikut.(ada digambar) (Cepatya,dan Jangan Asal Jawab Demi Point Gede)

Saya contohkan beberapa, sisanya bisa dicoba sendiri ya :)
1. m = Δy/Δx mAB = 4/2 = 2 mCD = 2/5 mEF = 3/5
2. m = Δy/Δx m = (y2 - y1)/(x2 - x1)
a. m = (0 - 3)/(0 - 1) m = -3/-1 m = 3
b. m = (-4 - (-1))/(-3 - (-8)) m = (-4 + 1)/(-3 + 8) m = -3/5
3.y = mx + b a. y = 5x - 3 m = 5
b. y = -3/2x + 3 m = -3/2
c. 2x + 5y + 12 = 0 5y = -2x - 12 y = -2/5x - 12/5 m = -2/5
1.
m = Δy/Δx
mAB = 4/2 = 2
mCD = 2/5
mEF = 3/5
2.
m = Δy/Δx
m = (y2 - y1)/(x2 - x1)
a. m = (0 - 3)/(0 - 1)
m = -3/-1
m = 3
b. m = (-4 - (-1))/(-3 - (-8))
m = (-4 + 1)/(-3 + 8)
m = -3/5
3.y = mx + b
a. y = 5x - 3
m = 5
b. y = -3/2x + 3
m = -3/2
c. 2x + 5y + 12 = 0
5y = -2x - 12
y = -2/5x - 12/5
m = -2/5
