Question 1143298: A medical clinic is reducing the number of incoming patients by giving vaccines before flu season. During week 5 of flu season, the clinic saw 85 patients. In week 10 of flu season, the clinic saw 65 patients. Assume the reduction in the number of patients each week is linear. Write an equation in function form to show the number of patients seen each week at the clinic.
f(x) = 20x + 85
f(x) = −20x + 85
f(x) = 4x + 105
f(x) = −4x + 105

Given answer choices that are all very different, it should be easy to find the right one if you understand the concept of slope.

Over a space of 5 weeks (from week 5 to week 10), the number of cases declined by 20, from 85 to 65.

That's a decline of 20/5 = 4 per week; only one answer choice shows a decline of 4 per week.
