Graph the solution sets of the following inequations:

x y - 2


Given x y - 2


yx + 2


Consider the equation y = x + 2


Finding points on the coordinate axes:


If x = 0, the y value is 2 i.e, y = 2


the point on the Y axis is A(0,2)


If y = 0, 0 = x + 2


x = - 2


The point on the X axis is B( - 2,0)


Plotting the points on the graph: fig. 5a


Now consider the inequality yx + 2


Here we need the y value less than or equal to x + 2


the required region is below point A.


Therefore the graph of the inequation x y - 2 is fig. 5b
