What is the distance between points a and b? units

we know that

the distance's formula between two points is equal to

substitute

therefore

the answer is

The distance between two point is .

Further explanation:  

The distance between two points is the modulus of difference of the given two points.

The distance between two points can be found by the distance formula as,

Here, are the points on the number line.

The distance cannot be negative therefore modulus is applied in the formula.

Step by step explanation:

Step 1:

First we determine the points from the given number line.

It can be observed from the given number line that there are two points one is on the left side of the origin and the second is right side of the origin.

The point is and the point is 1.

Step 2:

Now use the distance formula to obtain the distance between the two points  .

Here, the value of A is and B is 1.

Substitute the value of to obtain the distance as,

Therefore, the distance between two point is .
