Question

Find the distance between (8,13) and (1,-7)

Answer 1

use the formula \[\sqrt{(x2-x1)+(y2-y1)}\]

Answer 2

I got radical 13... I dont think thats right.

Answer 3

i think u got -13 am i right?

Answer 4

yes.

Answer 5

if u got radical -13 so u can say it has no real number solution cause minus is in radical

Answer 6

You must square (x2-x1) and (y2-y1) before adding and taking the square root
If you draw a picture, you might see you are using the pythagorean theorem.
