Question 173676
a)...P(1)=-3000(1)+17000=14000
.....P(2)=-3000(2)+17000=11000
.....P(3)=-3000(3)+17000=8000
:
b)this is written in y=mx+b format where P=y and x=n   remember m is the slope and b is the y intercept or in our case the P intercept
:
so the slope is -3000 and the P-intercept is 17000
:
c)the slope is the rate of change( every year that goes by the whole sale price loses 3000 dollars in value) and the P intercept is the starting price of the vehicle
