Answer:

The line segments are parallel.

Step-by-step explanation:

First, I never have graph paper when it is needed so I suggest Geogebra.com.

Now slope is found by rise over run so I took the points on the graph and counted where they intersected with any other points on the line. AB was 2/1 which means 2. I did the same for the other line segment and found 2/1 : 2. so both of the slopes are the same so you have parallel lines.
