## anonymous 5 years ago how to find the distance between points: (-3,2) and (3,-6)

1. anonymous

You need to use this equation: $d=\sqrt{(x _{2}-x _{1})^{2}+(y _{2}-y _{1})^{2}}$

woah

Find "distance" between x's and y's then use them as sides of a right triangle from -3 to 3 is 6 "distance" and from 2 to -6 is 8 "distance" 6 squared plus 8 squared is the "distance" squared. 36 + 64 = c squared, 100 is c squared, so c is 10

Where (x1, y1) is your first point, and (x2, y2) is your second point.

i got 100 inside the division bar now what?

6. anonymous

Its a square root - square root of 100 is 10.

7. anonymous

ok so the distance is 10?

8. anonymous

Yes - that's right!

9. anonymous

yay thanks
