Question

What is the distance between the points (-3,5) and (8,1)?

Answer 1

Answer: √137≈11.704699910719626

Hope this helps! :)

Explanation:

Use this formula to help you.

√(x1-x2)^2-(y1-y2)^2

Answer 2

Explanation:

A= ( −3 , 5 )

B = ( 8 , 1 )

The distance between points A and B is :

d(A,B)=137−−−√ ≈ 11.7047

Explanation

To find distance between points A(xA,yA) and B(xB,yB), we use formula:

d(A,B)=(xB−xA)2+(yB−yA)2−−−−−−−−−−−−−−−−−−−√

In this example: xA=−3 , yA=5 , xB=8 and yB=1 so:

d(A,B)d(A,B)d(A,B)=(8−(−3))2+(1−5)2−−−−−−−−−−−−−−−−−√=121+16−−−−−−−√=137−−−√
