Question 1143298
<br>
Given answer choices that are all very different, it should be easy to find the right one if you understand the concept of slope.<br>
Over a space of 5 weeks (from week 5 to week 10), the number of cases declined by 20, from 85 to 65.<br>
That's a decline of 20/5 = 4 per week; only one answer choice shows a decline of 4 per week.
