It is defined as the representation of the numbers on a straight line that goes infinitely on both sides.
The number line is shown in the picture, please refer to the picture.
As we have a point labeled P is placed at the third tick mark to the left of 0.
As we know the left side all numbers will be negative,
So increment of 0.5.
The P is representing the number = -(3×0.5) = -1.5
Thus, the P is representing the number -1.5 if the point labeled P is placed at the third tick mark to the left of 0.
