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

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. anonymous

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

3. anonymous

does that apply to question two too?

4. anonymous

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

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. anonymous

my ans is frist question means mid point

this is right fig.

13. anonymous

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

14. anonymous

why

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. anonymous

distance is 7.8

18. UnkleRhaukus

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

19. anonymous

Ooh thank you okay sunny thank you too

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