Answer 2

SOLUTION

TO CHOOSE THE CORRECT OPTION

Find d(A,B), If the co-ordinates of A & B are 7 & (-4) respectively. 

• 3

• 11

• - 11

• - 3

EVALUATION

Here it is given that the co-ordinates of A & B are 7 & (-4) respectively

Since co-ordinates of A and B are of different sign

So Both lies in opposite side of the origin

Also 7 > - 4

Hence the required d (A,B)

$\sf = |A - B|$

$\sf = |7 - ( - 4)|$

$\sf = |7 + 4|$

$\sf = |11|$

$\bf = 11$

FINAL ANSWER

Hence the correct option is 11
