What is x?
It is the number of years since purchase. Can this be negative?
NO! Years cannot be negative. So we disregard negative x-axis.
What is y?
It is the value of the computer at that year. A computer starts off with a positive value (y axis) and depreciates to 0 after some years. Can this be negative?
NO! At 0 value, the computer is worth nothing! There is nothing known as <em>negative </em>value. So we disregard negative y-axis.
