Question

find the distance between the pairs of points . (-1,-2) , (-1,0)​

Answer 1

Answer:

Distance between AB.

Solution :

Let point be,

A( -1 , -2 )

B( 1 , 0 )

We have Formula, (Distance Formula )

\tt \dagger \: \: \: AB = \sqrt{ {(x_2- x_1)}^{2} + {(y_2 - y_1)}^{2} }†AB=(x2−x1)2+(y2−y1)2

So,

\rule{90}1

\tt\longmapsto AB = \sqrt{{(1 + 1) }^{2} + {(0 + 2)}^{2} }⟼AB=(1+1)2+(0+2)2

\tt \longmapsto AB = \sqrt{4 + 4}⟼AB=4+4

\tt \longmapsto AB = \sqrt{8}⟼AB=8

\tt\longmapsto AB = 2 \sqrt{2} \: unit.⟼AB=2
