Standard form for linear equations | Algebra I | Khan Academy

When he speaks about getting the slope what I do is I know that A is the numerator on the slope, and B is the denominator. Then u have to know if the slope is positive or negative. If the equation is written with a plus sign in the middle, the slope is negative, I.e Ax + By. If the equation is written with a negative sign in the middle, I.e, Ax - By, you know it is positive. My maths teacher defaults to Ax - By = A(x coordinate) - B(y coordinate), I think I got that last part right ❤

i hate math

THANK YOU

I learned a way to identify both intercepts by inspection. Consider your line: 9x + 16y = 72. Divide both sides by 72, then (9/72)x + (16/72)y = 1. Rewriting (1/8)x + (2/9)y = 1. In this form the respective intercepts are the reciprocals of the coefficients of each term; i.e. x-int = 8, and y-int = 9/2. ◼

You helped my sister but you helped me in nothing why do you go soooo fast I have to keep replaying I am so gonna fail my midterm tomorrow whatever I’ll just go to summer school after I fail regents in 5 months since not you not my teacher can help my dumb self thx for nothing

I don't know if you read these, but the pace and effectiveness of the way you teach has helped me and so many others alot. We deeply thank you

I have a test tomorrow, this better work.
Edit: IT HELPED ME UNDERSTAND BUT I'LL UPDATE ON THE TEST SCORE-

I love u man keep up the good work

Can someone explain how he get 72? im confusing

My head is in pain

Not efficient

The dislikes are from the kids who were assigned this video by there teachers

Not me chillin while watching this(no sleep) 8hrs before deadline lol

how do i know what c is though DO THEY TELL ME OR WHAT

Im confused and cant understand anything im so dumb

you’re better then any teacher i’ve ever had

watch this at 144p

Thank you

I wish I had khan academy instead of edgenuity for online schooling :(

Thank you, it really helped me a lot

Thanks dude!

Is it just me or this guy writes incredibly good with a mouse?

The slope in standard form is really easy it is -A over B

GIVE US THE INFO!!! SOMETHING WE CAN USE!!!

WHY IS THIS ONE SO MUCH LOUDER

como seria tener clase virtual, mientras la cuarentena

Ax+by=C is the same thing as ax+by+C=0

I literally must need someone else to do it for me. This is so mind boggling to comprehend and my teacher gets mad when we ask for help. Can someone who is VERY math smart please help me? The stupid textbook is saying Ax+By=C and it's so different from this video.
I have adhd so I have trouble focusing and having a teacher who talks faster than the speed of sound and gets mad when people want help makes it worse.

Thank you so much! I have a math final tomorrow and was confused on this

I have a test today omg kms

what do you do when both intercepts are 0

These videos have saved me on so many test thank you

i’ve never had a good math teacher in my life, idk where i would be without this channel

Me remembering I forgot how to do standard form I have a test tomorrow and its 1 am. Thanks

Who else agrees his voice is smooth like butter 😂

Where did the 9 go in the equation 9x+16y=72?

Thanks for that!

Sal is a math teacher? 🤔

would it be the same with subtraction?

Thx dude my algebra one exam is tomorrow

I thought it was ax+by+c=0

Why am i cryin in the club rn

My textbook says standard form is Ax + By + C = 0

Bro thank u man I have a test tomorrow on all forms and converting them and didn’t understand anything the teacher said so I binge watched your vids and now feel ready to ace it

casually watching this an hour before an exam :')

I love it. Thanks ❤

my son had a 36 in math these videos helped him thanks you so much

Perfect

Still can't do this shit
