Question 626699: Find distance d (P1,P2) between the points P1 and P2 p1=(5,-1) p2=(3,5)
Answer by jim_thompson5910(35256)   (Show Source):
You can put this solution on YOUR website! d = sqrt((x2-x1)^2+(y2-y1)^2)
d = sqrt((3-5)^2+(5-(-1))^2)
d = sqrt((3-5)^2+(5+1)^2)
d = sqrt((-2)^2+(6)^2)
d = sqrt(4+36)
d = sqrt(40)
d = 2*sqrt(10)
So exact distance between the two points is 2*sqrt(10) units.
