Persamaan garis di bwah ini mempunyai gradien 1/3kecuali ... a. 3y-x=6 c.x=3y+2 b. 3y=x+1 d.3x=y-2 e. x-3y=1

Persamaan garis :
ax + by + c = 0
gradien, m = -a/b

a.
3y - x = 6
m = -(-1)/3 = 1/3

b.
3y = x - 1
3y - x + 1 = 0
m = -(-1)/3 = 1/3

c. m = 1/3

d.
3x = y - 2
3x - y + 2 = 0
m = -3/(-1) = 3
