Question

Help please?
if JKhas endpoints J(-2,3) and k(6,5), and LN has endpoints L(0,7) and N(4,1), then JK and LN have the same midpoint.

If GH has endpoints G(-8,1) and H(4,5), then the midpoint M of GH lies on the line y= -x+1.

Answer 1

Will fan and medal!!!

Answer 2

ok, what is the question

Answer 3

if JKhas endpoints J(-2,3) and k(6,5), and LN has endpoints L(0,7) and N(4,1), then JK and LN have the same midpoint. @DanJS

Answer 4

ok do you have to just show that? It is not asking anything

Answer 5

the question says show thateach question is rue

Answer 6

true*

Answer 7

The midpoint of a line segment is the average of the x and average of the y values..

two endpoints (x1, y1) and (x2, y2)

\[\large (\frac{ x1+x2 }{ 2 }~~~~,~~~~\frac{ y1+y2 }{ 2 })\]

Answer 8

Do that for both the segments to show they have the same midpoint value

Answer 9

okay, than you ::)

Answer 10

maybe make a graph too, welcome

Answer 11

If GH has endpoints G(-8,1) and H(4,5), then the midpoint M of GH lies on the line y= -x+1.

This you use the midpoint in the line equation and show that it is true...
midpoint - (x , y)
plug x and y into line, should be true
