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.

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

  2. 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.

  3. I learn better with person help not this and I still don’t get it it doesn’t cover it all of what we do in class so stupid

  4. 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.

  5. 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…

  6. i need help from a smart person on this



    and y= GOFUCK YOUSELF……thank you
