do you know the distance formula between two points?
OpenStudy (excalibur0126):
Nope
OpenStudy (en):
to find the distance between two point use the distance formula:\[D=\sqrt{(x _{2}-x _{1})^2+(y _{2}-y _{1})^2}\]
OpenStudy (en):
just substitute your points for example (a,b) are your first coordinates then they will be your \[(x _{1},y _{1})\] (c,d) are your second coordinates they will be your \[(x _{2},y _{2})\]
OpenStudy (excalibur0126):
So (-1-6)^2+(14-16)^2

-7^2+-2^2 or 49+4
OpenStudy (en):
the answer should be \[D=\sqrt{53}\]

Okay I think I get it, thanks :)

7.280109889 in decimal form
jimthompson5910 (jim_thompson5910):
it says `Find the distance ... to the nearest tenth`
so you'll have to convert to decimal form and round

7.280109889 just round this to the nearest tenth , then BOOM .. you're done
