Shows how to get the slope intercept equation of a line if given two points that are on the line.

Anyone else watching this during the 2020 Coronavirus lockdown because the Khan Academy videos make absolutely no sense and never actually explain how to solve for anything? Just me? Ok, I'l go back to online schooling now. (Thank you for this video though, it really helped)

oh my gosh thank you so much. You cant even comprehend how many weird vidios from 2004 i went through before i found this one!! Thank you!!

You're very welcome! Glad you found me.

Finally, someone who makes sense of it all THANKS. Very well Done...

Yes, I am the only one. Thanks for the comment.

[@daminion6730]

gee thanks it was much more better than all the other tutorials

[@stepbystepscience]

Glad you think so!

[@SmittenKitten.]

Thank you so much. This was so helpful. I was trying to graph it out and then count to find the intercept. This is SO MUCH EASIER (and faster).

[@stepbystepscience]

You're very welcome. Glad it helped!

[@melvingrace1390]

I'm having trouble finding the b sir

[@stepbystepscience]

Use one of the points for the x and y and the slope and solve for b.

[@display_nam3]

Thanks for the video! I never would have known how to get the y-intercept.

[@stepbystepscience]

Glad I could help!

[@StarsStars714]

Beautifully explained. Thank you.

[@jaspercalvit6397]

Hey man! What would you do if the slope ended up being undefined?

[@stepbystepscience]

Then it is a vertcal line and the slope is undefined. You can not divide by zero.

You can choose any X and Y for the Slope intercept form?

[@stepbystepscience]

yes.

I hope it goes well for you.

[@ahmedabouelnaga2407]

Does it matter which point You use to find b? for example cant you use the other point(3,2)?

[@mymymisa2101]

SO the end part when finding the y intercept you just add them to find b?

[@Prodnausy]

what software are you using to make this video

[@cthulhu7098]

Hey I'm just getting in to this sort of math and I was wondering what I would put in for the x and y values of this sort of equation

[@stepbystepscience]

That is a good question, you put in the x and y value for any point that lines on the line.

[@cthulhu7098]

[@ryanwelch2513]

Thanks so much I understand this topic now it the best man

[@stepbystepscience]

You are very welcome, Thanks for commenting. Glad it helped.

[@FN_Q]

I have a question but for finding b (the y intercept) can I choose randomly one of the two points? Because I noticed that each point using your method gives two different answers: one answer is positive and the other one is negative.

[@stepbystepscience]

Any point that you choose, along as it is on the line, will give you the same y-intercept.

[@SpaceVesselCommander0029]

yea I got a really weird improper fraction, but after swapping y1,y2 and x1,2 around I got a more reasonable fraction

[@carewilson9727]

How do you get the two

[@kalebcross6292]

brother you really helped me

[@stepbystepscience]

Great that I could do so, thanks for watching and commenting.

[@maxgrossman9576]

how did you get 3 for Y?

[@richardk.]

Thank you for explaining. 😀😀😀

[@eruntalion]

does it matter which set of points i use to calculate b or i can use whichever ones i fancy? nevertheless thank you very much for the easy and thorough explanation

[@stepbystepscience]

You can use any set of point as long as they are on the line.

How about using the equation: b = y1- { x1 times [(y2-y1) : (x2-x1)} and noting along the way that (y2-y1) : (x2-x1) = m
