Very helpful channel, so glad I found it! Studying for the GED, been trying for YEARS and was using a book that was confusing, and the videos that came with that book were confusing too, so I gave up for like 1-2 years, I was discouraged. I joined a class near me this year and they use a better book that's easier to understand, and they recommend the Khan Academy videos, but I happened to find YOUR channel when some Khan videos didn't make sense to me still. A friend who is in advanced math classes in university told me "search around some more, different instructors videos will connect differently with different people, find one that makes it easier for you to understand it, you need proper instruction to understand it" and I'm telling you, your videos are SO HELPFUL! very clear to understand, you break it down thoroughly so that I can understand the material properly! Thank you so much. I spent the past week watching different videos about the Slope formulas and getting them all mixed up, but your videos were the clearest and easiest to understand!

Thank you for breaking this down in terms I understand I'm struggling with Algebra so bad

Once again you are my superhero. Thank you!

You are awesome. My wife wonders why I watch you so much. keep it goin.

Thanks, that solved my problem and enabled me to move forward on linear equations. Definitely subscribing!

Your videos are great. Thank you.

You can also think of m as the “measure” of the line - the most critical feature, which is the Rate at which the y’s change (increase or decrease) as the x’s increase. An easy way to remember this is “rise over run” - for any x, y point, how much does the y rise (go up or down on the y axis) divided by how far it has “run” out on the x axis (from any prior x, y point) expressed as a rate of change (up is positive, down is negative). Y=mX + b Or Y1-Y0=m(X1-X0) This rate m is the essence of the line and never changes anywhere on the line, so it can be measured from any two points on the line B is a bit of an afterthought … it is just the point on the y axis where the line crosses (that axis)

Good practice. I personally prefer ax+by+zc +d =0. And yes, we just moved to R^3 planes, but this easily expands to R^n, which I expect to come up post High school pretty quickly 😊 and then the journey really begins 🎉 I struggled, but sticking with it, math opened my mind. There is so much to discover and math is the basics that will help unlocK a lot. Maybe feels extreme, but that is whet keeps me exploring. Check out Colllatz conjecture. So simple, so beautiful, yet unproved (not sure what emoji to put). Just keep at it, and who knows what😅 awaits 🎉

Couldn’t we just use(3,7) and plug it in y=mx+b with the slope to solve for b or the y-intercept

Hi, I have a question. I am consistently (operative word here) getting Point Slope equations wrong with +/- numbers. Do you have any videos that may help with this? I am trying to work the equations I have using this form because you said it is important to use this form. Using (4,-8) (8,5) I am coming up with y= 13/4x +26
