Answer:
12
Step-by-step explanation:
Let the two points be represented by (x1,y1) and (x2,y2).
Distance between the two points is given by the formula:
----------------- (1)
In this case x1=-2,y1=6,x2=-2,y2=18.
Substituting the relevant values in the formula (1),
distance = ![\[\sqrt{(-2-(-2))^{2}+(18-6)^{2}}\]](https://tex.z-dn.net/?f=%5C%5B%5Csqrt%7B%28-2-%28-2%29%29%5E%7B2%7D%2B%2818-6%29%5E%7B2%7D%7D%5C%5D)
= ![\[\sqrt{0^{2}+12^{2}}\]](https://tex.z-dn.net/?f=%5C%5B%5Csqrt%7B0%5E%7B2%7D%2B12%5E%7B2%7D%7D%5C%5D)
