The population of a town has approximately doubled every 17 years since 1950.
the equation P=
where Po is the population of the town in 1950, is used to model the population, P, of the town t years after 1950.
When t=17 yrs
P=2
for 1 year
The equation becomes
P = 
-------------(1)
Our original equation is
----------------------------------(2)
equating expression 1 and 2
Cancelling 
from both sides we get
t/17=k
⇒k=t/17 is the solution.
The general slope-intercept form equation is:
In this case, m=-2 and with the point (4, 10) we can find the value of b:
We found that b = 18, so:
Well is this like history
24)y=x-4
21) y=-3x+1
23) y=4/5x+6
The answer to m2=91 is 40.5
