Question

2. Find d (P,Q) if co-ordinate of point P = 7 and Q = -4.​

Answer 1

Answer:

p=7

q=-4

so

p×q

7×-4

d=-28

Answer 2

SOLUTION

GIVEN

The co-ordinate of point P = 7 and Q = - 4.

TO DETERMINE

d(P,Q)

EVALUATION

Here it is given that the co-ordinate of point P = 7 and Q = - 4

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(P,Q)

$\sf = |Q - P|$

$\sf = | - 4- 7|$

$\sf = | - 11|$

$\bf = 11$

FINAL ANSWER

Hence d(P,Q) = 11
