Question

What is the distance from point A (-2, 1) to point B (1, 3)?

Answer 1

`sqrt13`

Explanation:

To solve this problem we will use the distance formula:

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

We just plug in our two given points.
It doesn't matter which you choice to be `(x_2,y_2)` or `(x_1,y_1)`

For this case I'll let point B = `(x_2,y_2)` and point A = `(x_1,y_1)`

`sqrt((1-(-2))^2+(3-1)^2`

`sqrt((3)^2+(2)^2` = `sqrt(13)`
