On a school map, the points (-1, -9), (-1, -1), (7, -9), and (7, -1) represent the four corners of a sand park. What are the coordinates of the center of the sand park?

2. LoveToDance22

a. (-1, -5) b. (3, -4) c. (3, -5) d. (4, -4)

|dw:1345069632233:dw| find the midpoint distances, then add them to the bottom left coordinate

4. LoveToDance22

@completeidiot Is it c. (3,-5)?

Did you graph this on graph paper first? If you did, you would be able to figure it out really quickly.

6. LoveToDance22

I don't have graph paper, but I did it on regular paper (so the lines aren't completely exact) but I can't tell if its B or C

7. Hero

I would not attempt to do this without graph paper.

I am not sure about this, but maybe if you used the formula to find the midpoint of a segment, you'll probably get the center of the sand park. I am thinking the (-1,-1) and (7,-9)

9. panlac01

or (-1, -9) and (7, -1)

10. LoveToDance22

With (-1, -9) and (7, -1) I got (3,-5)

11. panlac01

12. LoveToDance22

@panlac01 for the other pair I got (3,1)

13. panlac01

are you sure? I am thinking it will be the same

14. LoveToDance22

Oh sorry lol, careless mistake, yeah there both (3,5). Thanks! :)

15. panlac01

3, -5

16. LoveToDance22

sorry -5, I'm bad at typing quickly

17. panlac01

k, that's how you would solve without the use of graphing paper

Thanks!
