Answer:
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−−−√
