Exercise 6.2

Solve the following inequalities graphically in two dimensional planes:

1.

Ans. Given:

Table of values satisfying the equation

	1	2
	4	3

Putting (0, 0) in the given in equation,

0 < 5

which is true.

Therefore, Half plane of towards origin.

---

2.

Ans. Given:

Table of values satisfying the equation

	1	2
	4	2

Putting (0, 0) in the given in equation,

which is false.

Therefore, Half plane of away from the origin.

---

3.

Ans. Given:

Table of values satisfying the equation

	0	4
	3	0

Putting (0, 0) in the given in equation,

which is true.

Therefore, Half plane of towards the origin.

---

4.

Ans. Given:

Table of values satisfying the equation

	5	6
	2	4
