the general function p(t)=640ekt is used to model a dying bird population, where p0=640 is the initial population and t is time measured in days. Supposed the bird population was reduced to one quarter of its initial size after 9 days. How long will it take before there are only 40 birds left in the population? Simplify your answer as much as possible

idk

step-by-step explanation:

i believe that the answer is

b. y-1=-2(x-4)

hope this !
