Question

Find the distance between the following two points:
(4,-1) and (7,-3)

Answer 1

`d = √(13)`

Explanation:

Distance Formula:
`d = √((x_2-x_1)^2+(y_2-y_1)^2)`

Simply plug in the 2 coordinates into the distance formula to find distance d:

`d = √((7-4)^2+(-3-(-1))^2)`

`d = √((3)^2+(-3+1)^2)`

`d = √(9+(-2)^2)`

`d = √(9+4)`

`d = √(13)`
