Example  I: Represent x > 4 on number line and x is a natural number.
solution:
If we take x = 0, we get 0 > 4. But 0 > 4 is not true. Therefore 0 is not a solution for the given inequation. Thus all the natural numbers greater than 4 are the solutions for the inequation x > 3.

Example  IV: Directions: Represent the following inequations on number line. 1. Represent x > 5 on number line and x is a natural number. 2. Represent x > 2 on number line and x is a natural number. 3. Represent x ³ 4 on number line where x Î R. 4. Represent x ³ 2 on number line where x Î R. 5. Represent x < 5 on number line, x is a natural number. 6. Represent x < 10 on number line, x is a natural number. 7. Represent x £ 4 on number line, where x Î R.
8. Represent x £ 9 on number line, where x Î R.
