[Video] Q2: Tracy collects, sells, and trades figurines, and she tracks the number of figurines in her collection on the graph below. on what interval did the number of figurines decrease the fastest?

Explanation for Question 2 From the Math (Calc) Section on the Official Sat Practice Test 8

So question two tells us about Tracy's figuring collection and in this graph, 2 we're graphing over a period of time. 3 How many figurines are in her collection? 4 And the question is asking us on what interval did the number of figurines 5 decrease the fastest. And so a good first step would be to decide, 6 okay, on what intervals are we decreasing it all because we can eliminate answers 7 that show intervals of increasing, right? 8 So it looks like we're decreasing from one to two and we're decreasing from 9 three to four. All the other ones show increases in the number of figurines. 10 So we can eliminate B and we can eliminate D. 11 And so now we just need to see which one did we decrease the 12 fastest on. And the one that we decreased the fastest on would drop the 13 biggest distance over the period of time. 14 Right? And so both of these intervals are one month. 15 So they're the same period of time, but it looks like between months, 16 three and four, we dropped more than between months, 17 one and two. And so for that reason, 18 our answer's going to be, see, we had the steepest or quickest drop, 19 um, between month, three and four.
