## anonymous 3 years ago How many units apart are the points (4, -3) and (-4, 3)?

Use: $\large Distance = \sqrt{(x_2 - x_1)^2+ (y_2 - y_1)^2}$ $\large x_2 = -4, x_1 = 4, y_2 = 3, y_1 = -3$ Plug in the values and find the distance..

0?

You are not taking care of negative signs.. $Distance = \sqrt{(-4-4)^2 + (3 - (-3))^2}$

-4 -4 = -8 and: 3 - (-3) = 3 + 3 = 6

so 2 ?

6. anonymous

How??

I think I have put square above the brackets in the formula. You have to square them first and then add them..

1 got 100

11. anonymous

Yes right.. Now take the square root of 100 ??

12. anonymous

50

13. anonymous

$$\sqrt{100} = 50 ??$$

14. anonymous

Do you know what is square root ??

15. anonymous

im rite?

16. anonymous

10

Yes now you are right.. Well Done . That is the distance between them..
