**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.
