Acountry's population in 1990 was 123 million. in 2002 it was 128 million. estimate the population in 2013 using the exponential growth formula.(p=ae^kt).round to the nearest millionth..

y=3x+4

step-by-step explanation:

given the points a(0,4) and b(-4, -8)

eqn of line ab: (y-4)/(x-0)=(-8-4)/(-4-0)

(y-4)/x=-12/-4=3

y=3x+4

time is equal to distance over rate so

t = d/r

need a little bit more information for the second question.
