How is the number of vertices for a prism related to the name of the prism

What are the coordinates of the point that is 1/3 of the way from a to b? a (2,-3) b (2,6)

Set $r$ is a set of rectangles such that (1) only the grid points shown here are used as vertices, (2) all sides are vertical or horizontal and (3) no two rectangles in the set are congruent. if $r$ contains the maximum possible number of rectangles given these conditions, what fraction of the rectangles in set $r$ are squares? express your answer as a common fraction.
