Question

Bagi2 poin!!! gradien garis dgn persamaan 4x-2y+8 = 0 adalah?

Answer 1

m = -a/b
m = -4/-2
m = 2

Gradien = 2

Answer 2

M = -a/b
m = -4/-2
m = 2

jadi gradiennya = 2

========================
atau
========================

titik potong smbu y, x = 0
4(0)-2y = -8
-2y = -8
y = 4

titik potong sumbu x, y = 0
4x-2(0) = -8
4x = -8
x = -2

didapat ( -2,0 ) dan ( 0,4 )

rmus mencari gradien
 = y2 - y1       4-0         4
    ----------  = -------- =  --- =  2
    x2 - x1       0+2         2
