## brianjr227 2 years ago Please help On a school map, the points (-7, -2), (-7, 4), (-1, -2), and (-1, 4) represent the four corners of a sand park. What are the coordinates of the center of the sand park? (-4, 3) (-3, 1) (-3, -3) (-4, 1)

1. brianjr227

this was one was the orginal I was gonna ask for help

2. warningiflirt

ok do u have graph paper?

3. brianjr227

No just line paper with me right now

4. warningiflirt

okay, then we use the midpoint formula, do you know it

5. brianjr227

I think can you write it and ill try

6. warningiflirt
7. warningiflirt

hold on ill try 2 solve it

8. brianjr227

@warningiflirt ok me too

9. warningiflirt

omg so frustrating im getting out the graph paper lol

10. brianjr227

haha

11. warningiflirt

(-4, 1), i graphed it and that's clearly the middle, im taking geometry now also so i have alot of graph paper :)

12. warningiflirt

this website has a calc 4 distance formula jst 4 2 coordinates it should help with basic probs :) http://www.mathportal.org/calculators.php

13. brianjr227

alright I'm trying to also see if i can get the same answer

14. warningiflirt

k you can make a graph on line paper i guess

15. brianjr227

lol i'll try

17. brianjr227

yes I got the same thing and that's how it came out on my paper- my bad graph but that looks correct to me

18. warningiflirt

|dw:1376431542941:dw| lol the midpoint it looks wayyyyy better on real graph paper

19. brianjr227

@warningiflirt thanks for helping me understand that better
