bunny12 · Answer

Do you know the distance formula?

sammypenguin · Answer

Yes (x2-x1)^2 + (y2-y1)^2

iceman35 · Answer

so apply the formula by plugging in each choice with (-2,-2)

sshayer · Answer

let distance d=5
(x1,y1)=(-2,-2)
let the other point be (x2,y2)
find (x2,y2)by the above formula
take $$d=\pm 5$$
find two values of( x2, y2)

sshayer · Answer

see which value matches above.

sshayer · Answer

$$d=\sqrt{( x2-x1)^2+\left( y2-y1 \right)^2 }$$
