1)The following graph shows the depreciation for the corporate airplane from 2006 to 2009. The plane was purchased new in 2006; therefore, x = 0 represents the year 2006. X – axis (horizontal) = years starting from 0 = 2006 and increasing by 0.5 years Y – axis (vertical) = price in $ amountsa)List the coordinates of two points on the graph in (x, y) form.(___, ___),(___, ___)b)Find the slope (rate of depreciation) of this line:Answer:Show your work here:c)Find the equation of this line in slope-intercept form.Answer:Show or explain your work here:d)If the rate of depreciation continues at the present rate, what will be the plane’s value in the year 2017? Show how to use the equation from part c) to obtain your answer.
