Question

Find the distance between (5,2) and (−1,9)

Answer 1

`d=9.21954`

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=√((-1-5)^2+(9-2)^2)`

`d=√((-6)^2+(7)^2)`

`d=√(36+49)`

`d=√(85)`

`d=9.21954`
