So, in order to use the site, you need to post the question you have whenever you post with the pre-paid question.  We are then able to give you answers pertaining to said question.  So in this case, you just need to post the question with your 

"what exactly am I doing wrong? I feel like I'm doing something wrong"


Then I can help you through whatever problem you have.

May 7th, 2015

So, since I'm betting your question wasn't what was wrong on the site, you can post your work/question and I can help you through via this thread.

I think you may have tried to attach a photo of your work, but the link does not work.

May 7th, 2015

Ugh. Yeah it didn't upload. 

May 7th, 2015

It's ok, if you make it a PDF or JPEG, You can attach it in a comment

May 7th, 2015

I reposted it lol 

May 7th, 2015

ah, ok, where exactly?

May 7th, 2015

I posted it as a new post

May 7th, 2015

I am trying to find the new post. Does it have the same title?

May 7th, 2015

I put okay here is the photo. Or something

May 7th, 2015

Are you able to request me?  The question is not available in the feed for me to go to.

So for 1-6, you will have 4 answers.  

May 7th, 2015

I'd personally graph them using https://www.desmos.com/calculator

To find the answers quickly(then you will catch the similarities between them as well)

May 7th, 2015

What!? Lol I shouldn't have used pen. Omg hahahaha 

May 7th, 2015

Yea, with circles you'll have 4 intercepts

May 7th, 2015

Ohhhh lucky me. 

May 7th, 2015

That is unless their centers are wayy out away from the axes

May 7th, 2015

It's ok, so let me show you the first one and you'll be like Ohhhhhh

May 7th, 2015

So here is the graph https://www.desmos.com/calculator/mk6ax6pncg


I have labelled the points required for this question.  

May 7th, 2015

Yayy! Help finally lol 

May 7th, 2015

Whoops, the labels did not stay.  Ok so the points are x intercepts (0,13) (0,-13)   y intercepts (13,0) (-13,0)

May 7th, 2015

So anywhere it crosses the axes is what we want, make sense?

May 7th, 2015

and I accidentally did it where it equals 169 not 144.  But it is the same pattern

May 7th, 2015

But what he wants  to do was just put 0,0 for the ones withouta number in   the variable

May 7th, 2015

Here is the 144 graph https://www.desmos.com/calculator/g2gazpcfrv

May 7th, 2015

That's not what the question is asking in 1-6.  In 1-6 it just wants the x and y intercepts

May 7th, 2015

The center of the circle is indeed (0,0) but it is not the intercepts

May 7th, 2015

Omg. Lol I hate this.  I don't get it that way though

May 7th, 2015

Yea, sounds like your teacher has you really confused.  

May 7th, 2015

Let me see, could you tell me the y intercept of this line?  y=3x+4?

May 7th, 2015

You should probably watch this video, it will help alot for understanding.    So this will explain where an x intercept is https://www.khanacademy.org/math/algebra-basics/core-algebra-graphing-lines-slope/core-algebra-graphing-intercepts/v/finding-x-intercept-of-a-line

This will explain finding the center and radius of a circle  https://www.khanacademy.org/math/algebra2/conics_precalc/circles-tutorial-precalc/v/radius-and-center-for-a-circle-equation-in-standard-form

May 7th, 2015

Hey sorry had to go to food science, but the 0,0 thing was right. I guess he just wanted it in that form 

May 7th, 2015

...that's not right though.  He must have changed the instructions and just wanted the center and radius.  

May 7th, 2015

But oh well, I'm happy you got it right!

May 7th, 2015

Also be careful on your centers.  The standard form of a circle is (x-h)^2+(y-k)^2=r^2   Where (h,k) is the center.  So make sure you watch for positives and negatives

May 7th, 2015

Yeah I think it was just the basic stuff he wanted

May 7th, 2015

Who knows, no offense but your teacher doesn't sound very good.  Sounds like an old tenured person who doesn't know the subject they are teaching if that was what he wanted in 1-6.  (unless he changed the directions)  If you end up needing more geometry help, try khanacademy.org  It has video tutorials for geometry in the US, and they actually make sense.


I hope you have good luck in the class!!!!!
