Will give brainliest! the equation r = 6t gives the number of albums released, r, by a record label over time in years, t. if you graph this relationship with time along the x-axis and the number of albums along the y-axis, which points lie on the resulting line? a) (5, 32) b) (7, 44) c) (11, 56) d) (15, 90) e) (10, 60) f) (12, 72)

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.
