Question

Find the coordinates of the other endpoint of each line segment given its midpoint and one endpoint

Midpoint (5,8), endpoint (13,10)


Midpoint (-7,6 ),endpoint (-9,9 )

Answer 1

(-3,6)

(-5,3)

Explanation:

1) 5= x+13/2

10= x+13

x = 10-13 = -3

8= y+10/2

16= y+10

y = 16-10 = 6

(-3,6)

2) -7= x-9/2

-14= x-9

x = -14+9 = -5

6= y+9/2

12= y+9

y = 12-9 = 3

(-5,3)
