the given set of data are ordered pairs ( one for x and the other one for y ). each ordered pair can be represented by a point in the coordinate system
the ordered pairs that we have are (2,2) , (4,2.5), (6,3.2), (8,3.5), (10,4.1) and (12,5). We can plot each ordered pair in the cartesian coordinate plane just like this:
