In a 2D plane, what does x > 2 represent?
In a 2D plane, all the points which have their x-coordinate more than 2 will be considered. This means we consider all those points in the first and the fourth quadrant which lie on the right side of the line x=2. But note that the points which lie on the line x=2 will not be considered as the equality is not included in the inequality given in the question.
