Algebra 21 - Slope

"Slope" is a fundamental concept in mathematics. Slope is often defined as "the rise over the run" ... but why?

This channel is brilliant. As a teacher, this video is really useful to teach someone the basics of derivates and then integrals. It just says everything and explain with images. Keep growing! :D

[Andybaby]

BRILLIANT, thank you. Can't believed I followed the whole thing without getting confused. Cant wait for the next one!!!

[MooMooMath]

Great explanation of slope. The graphics are very helpful. Thanks

[keneishapinto]

THANK YOU SO MUCH!! This helped me understand slopes easily without being confused! :)

that is my question: if "the slope of a line is the same at every point" for a line, how does it change as we move to the right? Because we are not changing the line. it is the same line. thank you.

I agree with Isaac:
I dread the day when WhyU will come to an end. I hope Abstract Algebra and Calculus videos come out!

[sighisoaraa]

Why are there so many dislikes? This video is incredibly helpful!

[armstrongsubero]

Excellent Video! This is the best explanation I have seen! You should seriously consider doing calculus videos!

[arifkizilay]

hello, I am not clear about the concept of elevation. Is it the same meaning as tilting? thank you.

[IsaacOrellano]

Your great thanx for all your help(: please don't stop your videos

[jamescarmody]

Oh my, you just saw the foundation of calculus!

Very exciting, don't you think?

[bradzepfan]

actually the 2 points don't have to be separated by 1 unit on the x-axis. this was a mistake on the part of the video?

[arifkizilay]

how is the elevation related to the slope? Does the line tilt to the right as the elevation increases? but how that is possible when the slope of the line is the same? One slope one line. Am I missing something here? thank you.

At 7:11 you drive chain rule principle

[StanleyHung]

What if you have a slope that's on the y line

[thuypham]

many thanks, please admin have many videos like this

[limdingwen]

new video I saw! :D
I like Why U, even my teacher uses it :D

[brunomartel]

Im gonna pay you a lot of money so you can make theses videos for the world

hi,
"the magnitude of the slope is determined by the amount of change in the line's elevation(?) over one horizontal unit of distance." With all respect, this sentence seems complicated and problematic. thank you
