You need the distance formula \[\huge~\rm~\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}\]

Then you have to do the math :)

x1= 2 x2=2 y1=1.2 y2=2.5 \[\huge~\rm~\sqrt{(2-2)^2+(2.5-1.2)^2}\]

the distance formula \[\huge~\rm~\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}\] We are trying to figure out the distance between the 2 point right? This formula will help us find the distance understood?

ok

So you do know that a coordinate is set up like this right? (x,y) <---

yea

Ok next we need know that this is how we determine what goes where.... (x1,y1)(x2,y2) understood?

x1= 2 x2=2 y1=1.2 y2=2.5 \[\huge~\rm~\sqrt{(2-2)^2+(2.5-1.2)^2}\] Here i have just used the numbers given in the directions ad substituted them into the formulathat i showed you earlier (distance formula)

From here you can solve it using a calculator or by hand whatever floats your boat :P let me know what you get :)
