Question

If the endpoints of AB are located at (0,7) and (8,8) what is the length of AB?

Answer 1

√65

Explanation:

The distance formula can be represented as

`\sqrt{(x_(2) -x_1)^2 + (y_2-y_1)^2}`

Taking (8,8) as (x₂, y₂) and (0,7) as (x₁, y₁), we have

`√((8 -0)^2 + (8-7)^2)\\= √(8^2 + 1^2)\\= √(65)`

as our answer
