Amedical 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
