There are two ways that a person can close their browser after watching this, either understanding everything, leaving a like, and stating how much the video helped in the comments, or you can leave more confused than ever and fail your math exam that's in 2 days. I'm in the first type, thanks Sal.
For the past week I haven’t understood a single thing in math. I have a test tomorrow and I was freaking out because I didn’t know how to do ANYTHING. this video helped me a lot!!!
4:44 *TO PEOPLE WHO DONT UNDERSTAND:* Basically, he's saying shade the bottom half of the boundary line because all of the solutions are less than () 4x+3 (y=4x+3) you would shade the top half
Or use vise versa : it depends on technique used to select the target region. For example here is an opposite technique ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE--fYv_ER9NA8.html
good morning fellow reader! is ur lucky day, im gonna tell you a legit shortcut on what to shade after you graphed the linear iniquality if y is on the right ex: y
thats a bad method because if you just copy this, it shows that you dont actually understand whats being done here and why you should be shading something. The best way to get good grades is by actually understanding the subject.
Khan you are AMAZING! Every time I want to learn something about math, all I have to do is search x plus khan (where x is the thing I want to learn) and BOOOM! Twelve or so minutes later I know it.
hello for everyone who didn't understand im going to explain it here clearly y = mx + n it refers to the position we start on the graph if we have n to 3 we start from 3 on the y vertical line now if m is 2 from the point we started we go 2 points up so we will be on the y =5 and one verticaly so x = 1 then y 7 and x 2 , y 9 then x 3 if m was -2 we would start at 3 and go down 2 verticaly and 1 horizontali y 3 x 0 then x 1 y 1 then x -1 y 2 ... now if x was 1 over 3 x that is a fraction and we start y 3 x 0 we would go y 4 x 3 then y 5 x 6 and so on for minus we would go down i hope this helps
What's interesting is that I'm a math teacher and I thought that this explanation was perfectly clear, but I'm reading the comments, and it looks like the commenters who are students are still confused. I will definitely break this down a little differently when teaching it.
When I'm in class everything goes in one ear and out the other and my teacher has been trying to teach this to the class for about a week and a half and we have to retake the test on it because so many people still didn't understand
I just wanted to say thanks for this bc it did help me understand the concept in a way, ik the creator might not see this but if you doooo then thanks honestly I would have failed school if these videos were never made lol
sir ,good explaination,but in short we can directly substitute (0,0) to find feasible region of inequation instead of substituiting all the values i.e -1,1.if inequation gets satisfaction by origin ,its feasible solution will be on side of origin or else another side .
I think I have it now! I was plotting correctly and using the dash and solid lines. But when it came to coloring it in on the computer it would not work. I think I was coloring the line too or not going above what was included. Still a little tricky.
