Step-by-step explanation:
The formula of the distance between two points
and
is 
To find the distance between two point:
- Put one of the two point as
- Put the other point as
- Substitute then in the rule of the distance and calculate the distance
∵ The two points are (18 , -2) and (6 , -10)
- Put (18 , -2) as
and (6 , -10) as
∴
= 18 and
= 6
∴
= -2 and
= -10
- Substitute them in the rule below
∵ 
∴ 
∴ 
∴ 
∵ (-12)² = 144 and (-8)² = 64
∴ 
∴ 
∵ 
∴
