Question
Every point on a number line represents:
✓
Answer
- a unique real number.
Solution:
On number line, we have $-\infty$ to $\infty$ numbers, consisting $-\infty...-4,-3,-2,-1,0,1,2,3,4...\infty,$ 1.12,1.14 and 1.41406532, 3.146201286295... etc. That means on number line, there are natural nmbers (1, 2, 3, 4 ...), integers, rational numbers $\frac{1}{2},\frac{1}{3},1.3333,$ irrational numbers 1.4148625385...
But if we see every number as a complete family, it becomes
Real numbers (any number which can be represent on Real axes)
So, every point on the number line reoresent a unique real number which contains every type.
Hence, option (a) is correct.
