1. Carilah nilai kemiringan (m) berikut ini; a) Y = 5 – 8x b) A (3,4) B (4,3) c) 2x – 3y + 2 = 0

1. Gradien

a) y = 8x-5
m = 8

b) A (3,4) B (4,3)
x1 = 3 , y1 = 4
X2 = 4 , y2 = 3

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

c) 2x - 3y + 2 = 0
-3y = -2x - 2
y = 2/3x + 2/3

gradien (m) = 2/3


Semoga Membantu :)
