@SnuggieLad r you okay over there?

snuggielad · Answer

OH ok...i just sat here wracking my brain trying to figure out why you needed it in radical form...you need to use the distance formula...
$$d \sqrt{(x_{2}-x _{1})+(y _{2}-y _{1})}$$
do you know how to put in the numbers?

anonymous · Answer

no

snuggielad · Answer

ok...give me a moment i am going to re make that formula

snuggielad · Answer

$$d \sqrt{(-3-1)^{2}+(-2-2)^{2}}$$
work that out...dont forget pedmas and i sure hope you know how to fix double negatives...

Denote point (-3,-2) as point (x1, y1).
Denote point (-1,2) as point (x2,y2).
