Represent to solution set of each of the following inequation graphically in two dimensional plane: `\ -3x+2ylt=6`

Explanation

The graphical representation of – 3x + 2y = – 6 is given in the figure below.
This line divides the xy-plane in two half planes.
Select a point (not on the line), which lies in one of the half planes, to determine whether the point satisfies the given inequality or not.
We select the point as (0, 0).
It is observed that, – 3(0) + 2(0) ≥ – 6 or 0 ≥ –6, which is true Therefore, the lower half plane is not the solution region of the given inequality.
Also, it is evident that any point on the line satisfies the given inequality.

Thus, the solution region of the given inequality is the half plane containing the point (0, 0) including the line. The solution region is represented by the shaded region as follows.
