tentukanlah nilai gradien di bawah ini ! a. y = 2×-8 b. 5×-10y-1 = 0 c. 2y+8×-5 d. 5x-3y=7 e. 9-5×+20y=0 tlg jwb bsk mau di kumpul

gradien= m
y = mx + c

a. y = 2×-8
m = 2
b. 5×-10y-1 = 0
-10y = -5x +1
y = (-5/-10)x - 1/10
m = 1/2
c. 2y+8×-5 = 0
2y = -8x +5
y = (-8/2)x +5/2
m = -8/2 =4
d. 5x-3y=7
-3y = -5x +7
y = (-5/-3)x -7/3
m = 5/3
e. 9-5×+20y=0
20y = 5x - 9
y = (5/20)x - 9/20
m = 5/20 = 1/4
