## xoalyssaxo1 3 years ago What is the midpoint of (–2, 0) and (4, –2)? (0, 0) (2, –2) (1, –1) (–6, 2)

1. xoalyssaxo1

What is the distance between points (12, 4) and (18, –1)? Round to the nearest tenth. 7.8 6.1 4.7 9.9

2. 03225186213

mid point x2-x1/2 y2-y1/2

3. xoalyssaxo1

does that apply to question two too?

4. 03225186213

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

You guys are the best thank you all. I will calculate and tell you if i got right then close. You're all lifesavers thank you!

10. sunnymony

my ans is frist question means mid point

12. sunnymony

this is right fig.

13. xoalyssaxo1

Thats what my teacher has for the question though and I got 1,-1

14. sunnymony

why

16. xoalyssaxo1

Unkle could you explain to me how to get the distance to second one with the formula I keep getting 45 am i supposed to square root it right?

17. sunnymony

distance is 7.8

18. UnkleRhaukus

$d=\sqrt{5^2+6^2}=\sqrt{25+36}=\sqrt{61}\approx8$

19. xoalyssaxo1

Ooh thank you okay sunny thank you too

20. sunnymony

this is true but solve |dw:1352555257628:dw|
