Question

if co-ordinates are given two points , P = -9 , Q = -1 then find d(P,Q) =?​

Answer 1

Answer:

Step-by-step explanation:

(-9,-1)

Answer 2

SOLUTION

GIVEN

The co-ordinates of P and Q are - 9 and - 1 respectively

TO DETERMINE

d (P ,Q )

EVALUATION

Here it is given that the co-ordinates of P and Q are - 9 and - 1 respectively

Since co-ordinates of P and Q are of same sign

So Both lies in same side of the origin

Also - 1 > - 9

Hence the required d (P ,Q)

$\sf = |Q - P |$

$\sf = | - 1- ( - 9)|$

$\sf = | - 1 + 9|$

$\sf = | 8|$

$\bf = 8$
