Question 256652: How would I find the midpoint of the lone segment having these endpoints (8,1) and (2,9)
Find the other endpoint of a line segment with given midpoint and one endpoint endpoint- (0,0) midpoint- (4, -3)
find the distance between the points (-3, -7) and (-4, 15)
Thank you

You can put this solution on YOUR website! How would I find the midpoint of the lone segment having these endpoints (8,1) and (2,9)
---
Let the midpoint be (x,y)
x is the average of 8 and 2 = (8+2)/2 = 5
y is the average of 1 and 9 = (1+9)/2 = 5
---
midpoint is (5,5)
------------------------------------
Find the other endpoint of a line segment with given midpoint and one endpoint endpoint- (0,0) midpoint- (4, -3)
---
Let the other endpoint be (x,y)
(0+x)/2 = 4 so x = 8
(0+y)/2 = -3 so y = -6
---
Other endpoint is (8,-6)
---------------------------------------
find the distance between the points (-3, -7) and (-4, 15)
d = sqrt(change in x)^2 + change in y)^2
d = sqrt(1^2 + 22^2)
d = sqrt(1 + 484)
d = 22.0227..
