8th grade on Khan Academy: 8th grade is all about tackling the meat of algebra and getting exposure to some of the foundational concepts in geometry. If you get this stuff (and you should because you’re incredibly persistent), the rest of your life will be easy. Okay, maybe not your whole life, but at least your mathematical life. Seriously, if you really get the equations and functions stuff we cover here, most of high school will feel intuitive, even relaxing. (Content was selected for this grade level based on a typical curriculum in the United States.)

About Khan Academy: Khan Academy offers practice exercises, instructional videos, and a personalized learning dashboard that empower learners to study at their own pace in and outside of the classroom. We tackle math, science, computer programming, history, art history, economics, and more. Our math missions guide learners from kindergarten to calculus using state-of-the-art, adaptive technology that identifies strengths and learning gaps. We’ve also partnered with institutions like NASA, The Museum of Modern Art, The California Academy of Sciences, and MIT to offer specialized content.

10. Chris Cano says:

very helpful, better than my pre tsi tutorial from plato.com…thank you

11. Shadow Noon says:

I love how my teacher shows us what something is called then Khan Teaches it to us

12. iLoveTurtlesHaha says:

We draw our y-axis, that’s my y-axis. OH GOD, I CAN’T TAKE IT ANYMORE. The constant repeating and repeating of every minute detail. We are not stupid, get on with it.

15. Jose Flores says:

this shit soo fucking confusing

16. Yafet Teshome says:

Helped me so much thanks

17. Mak Attack2o2 says:

Can someone help me with a problem like this?

y=-7x-1 and y=-3x-3

I don’t know how to graph this, and my teacher is anything but understanding and helpful.

18. Mak Attack2o2 says:

Thank you Khan Academy! Now, at least maybe, I won’t have a F in this class!

19. Mak Attack2o2 says:

What if all there is y=x+3 and y=2x? What do I do? There is no y intercept! so where does the 2 go?!😫😫😫😫 I hate my Algebra teacher now..She is heartless, and she doesnt even care…

20. Yousef Ayman says:

what is the name of khan academy app or the program that he use to make exampels

21. rabar omar says:

fuck school you will never need to know this in life

22. SwaggySavageYt says:

how do u fucking check the equations?

23. anti vicious says:

i need help from a smart person on this

y=1/3x-3/1

y=-x+1

and y= GOFUCK YOUSELF……thank you
