Question

Rate of Change , you are given the dollar value of a product in 2004 and the rate at which the value of the product is expected to change during the next 5 years. Write a linear equation that gives the dollar value (v) of the product in terms of the year
(Let t=0 represent 2000.)

2004 value= $156 with $4.50 increase per year

Answer 1

when t=4, v = 156
the equation of linear line
y = mx+b
m=slope
b = y-intercept or initial value
apply it to this problem
v = 4.5t + b
to solve for b, use given info (v=156 when t=4)
156 = 4.5(4) + b
b = 156 - 4.5(4)
b = 156 - 18
b = 138

Linear equation:
v = 4.5t +138
this means the product had value of $138 in 2000
