Tentukan gradien dari a. (-3,5) b. (0,-3 dan (-4,1) c. y=-1/2x+5 d.8=-4y+2x

M = gradien

a. (-3,5)
x = -3, y = 5

m = y/x
m = 5/-3

b. (0,-3) & (-4,1)
x1 = 0, x2 = -4, y1 = -3, y2 = 1

m = y2 – y1/x2 – x1
m = 1 – (-3)/(-4) – 0
m = 4/(-4)
m = -1

c. y=-1/2x+5

y=-1/2x+5 >> koefisien x = -1/2
m = -1/2

d. 8=-4y+2x
a = 2, b = 4

m = -a/b
m = -2/4
m = -1/2 [atau juga -0,5]
