Answer:
y= 327(0.85)^t
Step-by-step explanation:
Given data
Initial Population= 327
Increase= 15%
The model for an exponential function is represented as
y= P(1-r)^t
Substitute
y=327(1-0.15)^t
to be parallel
slope should be equal
for first question
y=1/3X +2
comparing with y=m1x+c
slope = 1/3
similarly for second equation
y=1/3x -4
comparing with y=m2x + c
m2= 1/3
since m1=m2
lines are parallel
