Well do you know what the distance formula is ?

ok lets do that part later
this is the distance formula
\[\huge d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}\]
you are given 2 coordinates
A(1,1) and B(7,-7).
(x1,y1)(x2,y2)

- pooja195

When you plug in the given coordinates you get this...
\[\huge d=\sqrt{(7-1)^2+(-7-1)^2}\]
Solve from here. :)

If you're stuck i can help you out! Just let me know! :)

sorry i am i really do suck at math...

- anonymous

so it's 10

- anonymous

My way is easier

- pooja195

@yomamabf they want you to use the distance formula read the directions. Congrats on giving the answer.

- anonymous

oh i alwys thought my way was the distance formula we didn't even learn the real formula

- cheesymcdouble

thank you so much @yomamabf
sorry her way IS easier @pooja195

- pooja195

@cheesymcdouble Read the directions that were provided they want the distance formula not her way.

- pooja195

@yomamabf we need to do what the directions say.

- cheesymcdouble

ok ok but it also wants the answer

- pooja195

you get the answer after you calculate this :
\[\huge d=\sqrt{(7-1)^2+(-7-1)^2}\]
Solve from here. :)

- cheesymcdouble

alright thanks.

- pooja195

Also theres another part to your question it asks explain the distance formula are you fimiliar with what the formula is used for?

- cheesymcdouble

wait what

- pooja195

This is why reading the directions is important.

Explain the distance formula

- pooja195

The distance formula is used to figure out the distance between 2 points. :)

- cheesymcdouble

ok thanks

- anonymous

fwiw both @pooja195 and @yomamabf applied the distance formula. The distance formula is just the specific application of the Pythagorean theorem when you have two points and want to know the distance between them. One method uses a formula, the other draws it out. Use the one that works best for you.

- cheesymcdouble

ya the drawing one actually helps me best.

- pooja195

@peachpi but they want the asker to use the distance formula .-.

- pooja195

Oh nvm lol i thought they wanted the physical formula and not the drawing...

- anonymous

yeah. it's the same either way. \(x_2-x_1=6\) and \(y_2-y_1=8\)

- cheesymcdouble

ok thanks guys

- anonymous

lol

- cheesymcdouble

|dw:1441482573482:dw|

- cheesymcdouble

so the answer is ten?

- pooja195

yep :)

- cheesymcdouble

ok um how did you that...

- cheesymcdouble

wouldnt it be 14

- anonymous

you don't add 6 and 8.
\[\sqrt{6^2+8^2}\]

- cheesymcdouble

um ok then how do you...nvm i suck at this stuff and i dont want to frustrate anyone

- anonymous

6² means 6x6
8² means 8x8

- pooja195

lol we are here to help! You wont frustrate people :)
6^2+8^2
36+64=100
srt100=10

- pooja195

*sqrt

- cheesymcdouble

ohhhh ok thanks @pooja195 and @peachpi this now makes sense to me
