You are given the dollar value of a product in 2016 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 t. (Let t = O represent 2010.) 2016 Value Rate $3,150 $450 increase per year Step 1 Recall that the slope of the line can be interpreted as a rate of change. In this case, the value increases as time passes and the rate of change is $450 per year. change in value (in dollars) rate of change = change in time (in years) 450 450 450 Therefore, the slope m of the linear function is m = 450 450 ep 2 We are to let t = 0 represent 2010. In 2016 the dollar value is given to be $3,150.

Step 1
Recall that the slope of the line can be interpreted as a rate of change. In this case, the value increases as time passes and the rate of change is $450 per year.

Therefore, the slope m of the linear function is m = 450

Step 2
We are to let t = 0 represent 2010. In 2016 the dollar value is given to be $3,150. Therefore, V = 3,150 when t = 6
This point on the graph of the linear function can be defined as (t,, v,) = (6 6, 3,150).
Step 3
Use the slope m = 450 and the point to express the relationship between variables V and t using the point-slope form.
V - V, = m(t - t,)
