Question

Find the missing endpoint and length of the line segment AB if the coordinates of A are (34,-22) and the coordinates of the midpoint are M(-2.5,10)?

The coordinates of the missing endpoint of the line segment AB are B( , )

The length of the line segment AB (to the nearest tenth) = units

Answer 1

let B=(x,y)
(-2.5,10)=[(34+x)/2 , (-22+y)/2]
therefore we have....
(34+x)/2 = -2.5 (-22+y)/2=10
34+x=-5 (-22+y)=20
x=-39 y=42
thus B's coordinate is (-39, 42)
