nilai p adalah? a. - 1 b. 1 c. - 3 d. 3

x1 = -3
y1 = 4p
x2 = p
y2 = -12

         m  =  (y2 - y1)/(x2 - x1)
         2   =  (-12 - 4p)/(p + 3)
2 (p + 3) = -12 - 4p
  2p + 6  = -12 - 4p
 2p + 4p = -12 - 6
         6p = -18
           p = -3  (C)


Semoga Membantu!!!

m = 2
x1 = -3
x2 = p
y1 = 4p
y2 = -12
m = y2 - y1 / x2 - x1
2 = -12 - 4p /p - (-3)
2p + 6 = -12 -4p
2p + 4p = -12 - 6
6p = -18
p = -3
