Answer:
r, a, t, i, o
Step-by-step explanation:
Looking back at the question before this, Among these points, circle the points where x<y (the first coordinate, x, is smaller than the second coordinate, y.) the points were a, t, o, i, r. Those are the circled numbers.
Looking at this problem now, we will count those letters up from the y axis, in an increasing order. (also it spells out ratio)
