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.

im doing grade 10 math but we have to deal with algebraic expressions could you do a video on this and let me know when done i need help with that ill give example of algebraic expression and also problems I have with it

It says to write standard form of the equation of each line given and y -intercerpt

Slope = - 1/4
Y-intercept = - 2
