Question

find distance between w the following pairs of points p(1,-3) and q (4,1)
​

Answer 1

Answer:

P≡(−5,7)

Q≡(−1,3)

∴d(P,Q)=

(−5−(−1))

2

+(7−3)

2

∴d(P,Q)=

16+16

∴d(P,Q)=

32

∴d(P,Q)=4

2

Answer 2

Answer:

5 is your answer

$P =(1,-3)\\Q =(4,1)\\\\d(P,Q) = \sqrt{(1 - (4))^{2}  +(7-3)^{2}} \\d(P,Q) = \sqrt{9 + 16} \\d(P,Q) =\sqrt{25}\\ d(P,Q) =5$
