Question

What is LN? The image consists of a number line labelled from negative 4 to positive 16 in the interval of two. Points L, M and N are marked -2, +6 and +12 respectively.

A . 14
B. 10
C. 16
D. 7

Answer 1

Answer: A) 14

========================================================

Step-by-step explanation:

Let's add point P at the location 0 on the number line.

The distance from L to P is 2 units. We can say LP = 2, ie segment LP is 2 units long.

Similarly, segment PN is 12 units long

Refer to the diagram below

The segments LP = 2 (red) and PN = 12 (blue) are then added to get the total distance from L to N. That total distance being LN = LP+PN = 2+12 = 14.

Point M is not used at all.
