Question 2
The distance between the points A(0,6) and B(0, -2) is:
(A) 6
(B) 8
(C) 4
(D) 2

Answer 1

$\because \text{Distance between the points}(x_1,y_1)and(x_2,y_2),d=\sqrt{(x_2-x_1{)}^2+(y_2-y_1{)}^2}Here,x_1=0,y_1=6and{x}_2=0,y_2=-2\therefore \text{Distance between}A(0,6)andB(0,-2),AB=\sqrt{(0-0{)}^2+(-2-6{)}^2}=\sqrt{0+(-8{)}^2}=\sqrt{8^2}=8$
