It is clear from the given graph that it is showing the relation between the annual sales corresponding to various years starting from the year 2010.
Here, the x-axis represents “Year” and the origin that is the point ‘O’ is the starting point which is the year 2010 as mentioned in the question. And each division corresponds to increment of a year which means ‘0’ denotes the year 2010, ‘1’ denotes the year 2011, ‘2’ denotes the year 2012, etc.
Also, the y-axis represents the “Sales (in millions $)”. Each division corresponds to an increment of a million $ sales which means ‘1’ denotes 1 million $ of sales, ‘2’ denotes 2 million $ of sales, etc.
Now, the ordered pair is the co-ordinate of a point which is represented in the form of (x, y).
