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:
[tex]\[\sqrt{(x2-x1)^{2}+(y2-y1)^{2}}\][/tex] ----------------- (1)
In this case x1=-2,y1=6,x2=-2,y2=18.
Substituting the relevant values in the formula (1),
distance = [tex]\[\sqrt{(-2-(-2))^{2}+(18-6)^{2}}\][/tex]
= [tex]\[\sqrt{0^{2}+12^{2}}\][/tex]
=12
