## anonymous one year ago find the distance between the points (9,9) and (-7,-7)

1. pooja195

Use the distance formula $\huge d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}$

2. pooja195

(x1,y1)(x2,y2)

3. anonymous

so how would I enter the values

4. pooja195

$\huge d=\sqrt{(-7-9)^2+(-7-9)^2}$

5. anonymous

ok

6. pooja195

Yea....now solve that :)

7. anonymous

why dont u solve it for him... Qualified helper O_O

Really? That's all I look for 90% of the time

11. pooja195

@drkid15 have you solved it?

12. anonymous

wouldnt it just be (-7 - 9) + (-7 - 9)? cause its sqrted?

13. anonymous

d = -32?

14. anonymous

15. anonymous

im guessing so

16. anonymous

is ur question multiple choice?

17. anonymous

no

18. pooja195

Why not try solving it yourself?

19. pooja195

If you need help i can GUIDE you.

20. anonymous

idk how

21. anonymous

Im, 99% sure its -32, but I am blond... so I might be stupid

22. anonymous

can u just guide me plz

23. anonymous

Alright, so the equation is $D = \sqrt{(x2-x1)^{2} + (y2 - y1)^{2}}$ right?

24. anonymous

D is the distance between 9,9 and -7,-7

25. anonymous

both of those sets have an x and a y its like this (x,y)

26. anonymous

but since theres 2 sets, were gonna label it like (x1,y1) and (x2,y2)

27. anonymous

Are you paying attention Drkid15?

28. anonymous

yes

29. anonymous

For the equations we have 9,9 as the first pair, so it takes over the x1 and y1

30. anonymous

can u show me what it looks like when u enter the values

31. anonymous

$D = \sqrt{(9 - (-7))^{2} + (9 - (-7)^{2}}$

32. anonymous

By the way yes, the -32

33. anonymous

thx

34. anonymous

o wait no
