1.Carilah gradien setiap garis a.y=3x-4 b.2y=-4x+8 c.2x-4y-1-0 2.Diketahui titik A(2,-4),B(6,8),C(-3,5) a.Tentukan gradien garis AB b.Tentukan gradien garis AC

1. carilah gradien setiap garis
a. y=3x-4
m=3
b. 2y=-4x+8
y=-4/2x + 8/2
y=-2x + 4
m=-2
c. 2x-4y-1=0
4y= 0 - 2x + 1
y= -2/4x + 1/4
y= -1/2x + 1/4
m= -1/2

2. a. y2 - y1
--------------
x2- x1
= 8-(-4) = 12 = 3
--------- -------
6-2 4

b. y2 - y1
------------
x2 - x1

= 5-(-4) = 9 = 1
--------- ----- ------
-3-2 -6 -3

c. y2 - y1
-----------
x2 - x1

= 5-8 = -3 = 1
-------- -------- -----
-3-6 -9 3
