**Definition of Distance Formula**

- The formula , which is used to find the distance between two points (
*x*_{1},*y*_{1}) and (*x*_{2},*y*_{2}), is called the Distance Formula.

- The distance between the points (1, 3) and (2, 5) is

**Solved Example on Distance Formula**

What is the distance between the points A (4, 6) and B (- 2, - 2)?

Choices:

A. 10

B. 6

C. 8

D. 4

Correct Answer: A

Solution:

Step 1:(x_{1},y_{1}) and (x_{2},y_{2}) = (- 2, - 2)

Step 2:Distance between the two points can be found using the distance formula .

Step 3:So, AB = = 10 units.
