gradien dari persamaan garis _2x_6y+5=0

Persamaan garis 2x + 6y + 5 = 0 -> Ax + By + C = 0

Gradien = -A
___
B
= -2
___
6
= -1
__
3
= 3
__
-1
= -3

maaf kalau salah

gradien garis :
-2x -6y + 5 = 0

m = - a/b
m = - (-2)/-6
m = 2/-6
m = - 1/3


f(x) = 3x - 1
f(1) = 3.1 -1
       = 3 -1
       = 2

mau tanya lagi ?
