Observe that the points (10,12), (11,13),(12,14),(13,15) is of the form (x,x+2).
This means these points refers to direct variation.
Observe that the points (2,18), (3,12), (4,9), (6,6) is of the form (x,36/x).
This means these points refer to inverse variation.
There is no specific pattern followed in the points (6,4),(0,5), (4,6), (8,7), (2,8). This means these points are neither direct variation nor inverse variation.
