Koordinat titik tengah antara titik (4,-5) Dan (-1,0) adalah?

jawab

A(4,-5)
B (-1,0)

C titik tengah AB

C = 1/2 ( A + B)

C = 1/2 [ (4, - 5) + (-1, 0) ]

C = 1/2 [ (4 - 1) , (-5 + 0) ]

C = 1/2  (3, -5)

C = { 3/2, - 5/2 }

A titik tengah (4,-5) dan (-1,0)
A = 1/2 [( 4,-5) + (-1,0)]
A = ( 1/2(4 - 1) , 1/2((-5)+0)}
A = ( 1/2 (3) , 1/2 (-5))
A = 3/2, -5/2
