Question

Find the distance between A(2, -9) and B(-5, 7) on a coordinate plane d=?

Answer 1

`d=17.4642`

Explanation:

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

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

`d=√((-5-2)^2+(7-(-9))^2)`

`d=√((-7)^2+(7+9)^2)`

`d=√(49+(16)^2)`

`d=√(49+256)`

`d=√(305)`

`d=17.4642`
