tolong dijawab ya..bsk dikumpulin

a) mDE = mFG
( y2 - y1 / x2 - X1 ) = ( y2 - y1 / x2 - X1 )
( 2-6 / 8-p ) = ( 3+1 / -2p-p )
( - 4 / 8-p ) = ( 4 / - 3p )
-4 ( - 3p ) = 4 ( 8 - p )
12p = 32 - 4p
12p + 4p = 32
16p = 32
p = 2

b) mDE = - 4 / 8-p
= - 4 / 8-2
= - 4 / 6
= - ⅔
mFG = 4 / -3p
= 4 / -3(2)
= 4 / - 6
= - ⅔

c) belah ketupat
