Answer:

B. d(B, C) = BC = |6 – 1|

D. AB + BC = AC

Step-by-step explanation:

Given that:

On a number line :

Point A = - 2

Point B = 1

Point C = 6

Distance BC = d(B, C) = |6 - 1| = 5

Distance AB = |-2 - 1| = 3

AB + AC ;

AB = 3 ; AC= |-2 - 6| = 8 ; BC = |1 - 6| = 5

3 + 8 = 11

HENCE

AB + AC ≠ BC

AB + BC = AC

AC = |- 2 - 6| = 8

AB = 3 ; BC = |1 - 6| = 5

3 + 5 = 8

Hence,

AB + BC = AC
