shadowlegendx · Answer

We could use the Distance Formula, have you seen it before?

abbster2015backup · Answer

Yes I have seen it before

shadowlegendx · Answer

We could do that, or make a triangle

abbster2015backup · Answer

A triangle?

shadowlegendx · Answer

Have you heard of the Pythagorean Theorem?

abbster2015backup · Answer

Ohhhhhh yeah I know what that is.

abbster2015backup · Answer

$$a ^{2}+b ^{2}=c ^{2}$$

shadowlegendx · Answer

How do you think we might be able to solve this, using the Pythagorean Theorem?

abbster2015backup · Answer

Well, I know how to solve it once I plug in the numbers but I am not sure right now where to put the numbers, but I know we have to plug them in

shadowlegendx · Answer

I'll give you a hint. Here are the two points on a graph http://prntscr.com/b0o4bo

shadowlegendx · Answer

That red line is the distance between the two points, but could it also be?

shadowlegendx · Answer

what could it also be

shadowlegendx · Answer

I have to go soon, and you're offline, so I'll provide you with the proper information

abbster2015backup · Answer

Sorry I am online, my internet was acting up

shadowlegendx · Answer

The distance between the two points, is the hypotenuse of a triangle http://prnt.sc/b0o3zf

abbster2015backup · Answer

Ohhhhhhhhh

abbster2015backup · Answer

They both meet at -5, 6

shadowlegendx · Answer

http://prntscr.com/b0od3z

abbster2015backup · Answer

I mean -5, -6 right?

shadowlegendx · Answer

yeah

shadowlegendx · Answer

You see how it works though, right?

abbster2015backup · Answer

Okay, so is that what I plug in for the therom? And yeah

shadowlegendx · Answer

Use the Pythagorean Theorem, yeah. You get the sides by counting the units on each side. Then use them to calculate the hypotenuse

abbster2015backup · Answer

Ohhhhh so it would be C, 9.0 units!

shadowlegendx · Answer

How did you get that?

abbster2015backup · Answer

I counted the units on each side to caluculate the hypotenuse

abbster2015backup · Answer

Oh wait, ugh I am mixing this up sorry, wrong answer

shadowlegendx · Answer

You can count for these

|dw:1462474609145:dw|

but not these

|dw:1462474622346:dw|

shadowlegendx · Answer

Has to be a straight line, with an undefined slope, or a slope of 0

shadowlegendx · Answer

Aka, it goes straight up and down on the y axis, or straight left and right on the x axis

shadowlegendx · Answer

I gtg, use

8^2 + 6^2 = c^2

With c being your answer

abbster2015backup · Answer

Okay, thanks :)

abbster2015backup · Answer

I was just about to do that lol

abbster2015backup · Answer

Ah, I got 100 squared. I think I am doing this all wrong

abbster2015backup · Answer

Wait, unless I fix it so it equals D
