A(-3;1)
b(-6;0)
c(-5;-3)
d(-2;-2)
N = Number of years = 80 - 55 = 25
A = $400,000
r = 6% = 0.06
A = P(1 + r)^n
400,000 = P(1 + 0.06)^25 = P(1.06)^25 = 4.292P
P = 400,000 / 4.292 = $93,200
It would be 2*(5^2)
(2 multiply to (5 rise to the power of 2))
Hope that help.
Slope is 7/3 and y intercept is -3.
