Question

Find the distance between the following points (1 , 6) and (13 , -3)

Answer 1

15 units

Explanation:

`distance \: between \: 2 \: points \\ = \sqrt{(x1 - x2)^(2) + (y1 - y2)^(2) }`

Using the formula above, distance

`= \sqrt{ {(13 - 1)}^(2) + {( - 3 - 6)}^(2) } \\ = \sqrt{ {12}^(2) + {( - 9)}^(2) } \\ = √(144 + 81) \\ = √(225) \\ = \textbf{15 units}`
