bunyonb 2 years ago What is the distance between the points (-1, -5) and (8, 7)? A: 9 B: 15 C: 3 D: 21

1. bunyonb

@VlPatton ey come here

2. Joel_Atkins

As in co-ordinates?

3. bunyonb

yes

4. bunyonb

Use distance formula right?

5. Joel_Atkins

Depends if that's all the information they gave you.

6. bunyonb

according to @VlPatton that is all

7. VlPatton

Yes lol

8. bunyonb

This is multiple choice or what?

9. Joel_Atkins

If that's all they gave you then the distance formula will give you you're answer. It only varies if they give you a graph of chart.

10. Joel_Atkins

http://www.purplemath.com/modules/distform.htm If you're not too familiar, it explains about the formula here.

11. bunyonb

Ok i know purplemath

12. Joel_Atkins

I would have worked it out myself for you, but I'm currently at work and I can only help with things off the top of my head, or that I can work out quickly on a notepad.

13. bunyonb

Yes I am planning to work it out for Patton here. I just wanted to confirm that i need to use Distance formula
