Answer:
Midpoint of LM is (-3-1).
Explanation:
LM has endpoints L(-11) and M(-5-3)
We have to find the coordinates of mid point of LM
If a line segment has two end points (x,y) and (x',y') then x-coordinates of the midpoint will be
x =

and y coordinates will be
Y =

Now we put the values of endpoints to find midpoint of LM.
X =
=
= -3
Y =
=
= -1
Therefore, mid point of LM is (-3-1).
