A group of students is collecting books to add to their librarby. The table shows the number of books in the librarby after 1, 3
, and 5 days. If the relationship between days and books continues to be linear, which ordered pairs could appear in the table? Select all that apply. (You like my Undertale reference? Will give Brainliest if you provide an explanation)
Here are the points it gives: (0,8), (2,23), (4,32), (6,48), and (7,48)

Notice that every pair of point (x, y) in the original picture, has become (-y, -x) in the transformed figure.
Let ABC be first transformed onto A"B"C" by a 90° clockwise rotation.
Notice that B(4, 1) is mapped onto B''(1, -4). So the rule mapping ABC to A"B"C" is (x, y)→(y, -x)
so we are very close to (-y, -x).
The transformation that maps (y, -x) to (-y, -x) is a reflection with respect to the y-axis. Notice that the 2. coordinate is same, but the first coordinates are opposite.
