Question 627044: find JK if j(-3,-4) and k(-7,5)
Answer by jim_thompson5910(35256)   (Show Source):
You can put this solution on YOUR website! I'm assuming you want to find the length of segment JK. This is the same as finding the distance between the two points.
d = sqrt((x2-x1)^2+(y2-y1)^2)
d = sqrt((-7-(-3))^2+(5-(-4))^2)
d = sqrt((-7+3)^2+(5+4)^2)
d = sqrt((-4)^2+(9)^2)
d = sqrt(16+81)
d = sqrt(97)
So exact distance between the two points is sqrt(97) units.
This approximates to 9.8488578 units.
