Question

How do you find the distance between (7,-10), (-10, -4)?

Answer 1

`5\sqrt13\ \text{unit`

Explanation:

The distance between two points `(x_1, y_1)\equiv(7, -10)` & `(x_2, y_2)\equiv(-10, -4)` in XY-plane is given by following general formula

`\sqrt{(x_1-x_2)^2+(y_1-y_2)^2}`

`=\sqrt{(7-(-10))^2+(-10-(-4))^2}`

`=\sqrt{325}`

`=5\sqrt13`
