<u>Answer:</u>
(0.5, -0.5)
<u>Step-by-step explanation:</u>
We are given a line segment on the graph with two known points (ending points) and we are to find its mid point.
We know the formula for the mid point:

Substituting the coordinates of the given points in the above formula:
Mid point =
= (0.5, -0.5)
