Question

how do I find my distance using the distance formula with points (-1,1) and (2,-3) also would the answer be 5 or the square root of 5?

Answer 1

\(\Large d=\sqrt{(x _{2}-x _{1})^{2}+(y _{2}-y _{1})^2}\)

Just plug in the x's and y's of your two points: (-1,1) and (2,-3)

\(\Large d=\sqrt{(-1-2)^{2}+(1-(-3))^2}\)

and simplify! What do you get for the answer?

Answer 2

is it 5 or 5 squared?

Answer 3

hello

Answer 4

what did you get? the formula above is clear, isn't it?

Answer 5

yes I got the answer 5 but is it s?

Answer 6

5 squared?

Answer 7

the distance is 5 units

Answer 8

no, you took the sqrt root of 5 squared to get 5. that is the distance

Answer 9

ohhh ok thank you

Answer 10

you're welcome

Answer 11

Do you understand why? How to get that from the formula?

\(\Large d=\sqrt{(-1-2)^{2}+(1-(-3))^2}=\sqrt{(-3)^{2}+(4)^2}\\\Large =\sqrt{9+16}=?\)

Answer 12

yes ty
