The following graph shows how a 4color web printing press depreciates from the year 2006 to the year 2010. It was purchased new in the year 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 $ amounts from 12,000 to 120,000
a) List the coordinates of any two points on the graph in (x, y) form. The numbers on the horizontal axis are 0.5, 1.0, 1.5, 2.0, 2.5, 3.0, 3.5, and 4.0.
