Question

The co-ordinates of point A and B are 4 and -8 respectively . Find d(A,B).
Plz answer it fast.

Answer 1

d(A, B)=4-(-8)
d(A, B)= 12

Hope this helps you dear !✌

Answer 2

$\rm\textsf\green{Solution }$

$\rm\textsf \blue{ The\:two\:points \:x_{1}\: and\: x_{2}lie on \: \\ the \: X-axis\:\\then \: distance\\ between\: them \: is \: |x_{2}-x_{1}|}$

$\rm\textsf{ Here x_{1}=4 \:and\: x_{2} = -8 }$

Now ,

Distance = $| -8 - 4 |$

= $|-12|$

= 12

Therefore ,

$d( A,B ) = 12$
