What is represented in the following coordinated plans?

It is a part of the line bounded by the points A and B. By definition, it is a line segment between A and B.
The graph represents the line segment between A and B.

The line is not bounded. It is a line a line that passes through two points A and B.
The graph represents the line that passes through A and B.

It is a part of a line that starts at a point A and continues on one direction. Therefore, it is a ray.
The graph represents a ray that goes from A to B.

We can see two lines on the graph. Since the lines will never meet, we can deduce that they are parallel.
The graph represents two parallel lines.

The line is bounded by the points A and B. Since it has both a magnitude and direction, we can conclude that it is a vertex.
The graph represents a vector from A to B.

The graph represents two lines that meet at point A.

It is a line and a point lying outside the line.
The graph represents a line and a point lying outside the line.
