Question

do anyone know the distance formula for (-5,2) and (-9,9)

Answer 1

Distance formula is not specific to 2 points.
Understand this. YOU NEED TO FIND THE **DISTANCE** between the 2 points.

Distance formula is like this
\[\sqrt{(x2-x1)^2 + (y2-y1)^2}\]

For any 2 points
(x2,y2) = [here] = (-5,2)
(x1,y1) = [here] = (-9,9)

Put them in the distance formula and you'll get the distance. :)

Understood? :)

Answer 2

yes working it out now

Answer 3

@AkashdeepDeb i got -65

Answer 4

I think you got
\[\sqrt 65\]

And that is the distance.

Answer 5

18
13
8
11
these are the choices

Answer 6

It is APPROXIMATELY 8.
\[\sqrt 65 \approx 8 = \sqrt 64 \]
Understood? :)
