## anonymous one year ago Point R is at (2, 1.2) and Point T is at (2, 2.5) on a coordinate grid. The distance between the two points is ____. (Input numbers and decimal point only, such as 8.2.)

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

2. pooja195

Then you have to do the math :)

3. pooja195

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

4. pooja195

Solve

5. anonymous

i still dont understand

6. pooja195

Ok are you fimiliar with the distance formula?

7. anonymous

nope

8. pooja195

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?

9. anonymous

ok

10. pooja195

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

11. anonymous

yea

12. pooja195

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

@nomymalik

14. pooja195

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 :)
