The distance from -7 to 5 on a number line is 12 units. This distance between two integers is calculated by using a number line and the absolute value of the difference between those two integers.
What is a Number line?
- A number line is a graph for the real numbers.
- It is used to represent the integers on it at a regular interval.
- It is also used for finding arithmetic operations like the addition and subtraction of integers.
- The positive integers lie on the right side of the number line and the negative integers lie on the left side of the line
- The zero lies at the center of the line which separates the positive and negative integers.
How to calculate the distance between two integers on a number line?
- For calculating the distance between two integers, count every integer in between them
- A faster way of finding the distance between the two integers is by taking the absolute value of their difference
- If A and B are two integers, then the distance between them is given by |B - A|
Calculating the distance from -7 to 5 on the number line:
⇒ | 5 - (-7) |
⇒ | 12 |
= 12 units
Therefore, there are 12 units in between the given two integers -7 and 5 on a number line which is shown below
