-2-2 2
2(3-p) = 1(-2-2)
6-2p = -2-2
-2p = -4-6
-2p = -10
p. =5
B(2,p)
m = 1/2
Jawab : (-2,3) --> x1 = -2 y1= 3
(2,p) --> x2 = 2 y2= p
m = y1 - y2
-----------
x1-x2
1/2 = 3-p
------
-2-2
1/2 = 3-p
-----
-4 (dibuat perkalian silang)
1(-4) = 2(3-p)
-4 = 6 - 2p
-4 -6 = -2p
-10 = -2p
-10 -2p
----- = ------
-2 -2
5 = p
p = 5
Jadi nilai P adalah 5.
sorry klau susah dibaca, soalnya susah pkai simbol
