tentukan gradien garis yg melalui titik 0,0 dan 10, -15

Bab Persamaan Garis
Matematika SMP Kelas VIII

(x1, y1) = (0, 0)
(x2, y2) = (10, -15)

gradien = m = (y2 - y1)/(x2 - x1)
                    = (-15 - 0) / (10 - 0)
                    = -15/10
                    = -3/2

Gradien (m) garis mlalui 2 titik, (x1,y1) dan (x2,y2) :

m = ∆y/∆x = (y2 - y1)/(x2 - x1)

••
(x1,y1) = (0,0)
(x2,y2) = (10,-15)

m = ∆y/∆x
m = (-15 - 0) / (10 - 0)
m = -15/10
m = -3/2 ✔
