A video that teaches the mathematical concept of the slope of a line. I made it for one of my NYU classes. Now I have my Master's in Math Education and can start my teaching career!

  • Do you ever do individual tutoring? I could use some; with or without the cat

  • Yes, see my website. The link is in the comments. Click on "math tutoring" in the right hand navigation column.

  • How about the horizontal line, then? Can we also say that if the horizontal line moves to the right it will have a slope of positive infinity and if it moves to the left the slope would be negative infinity? That would mean that both the vertical and horizontal lines would have the same slope. From your video, the slope of a horizontal line is zero. It would have been better if you also discuss the real slope of a vertical line.

  • Dude, it's a four-minute video. What more do you want? Stop complaining. And, no, a horizontal line would be +0 and -0, not infinity.

  • Sorry but I think if you have a vertical line, the slope would be undefined. Since slope= rise/run, therefore you will hve a value for rise but zero value for run. Any number divided by zero is considered undefined.

  • That's true. Technically, the slope "approaches" infinity as it becomes more vertical. An actual vertical line has an undefined slope. I didn't want to bother with the distinction in my elementary video.

    Also, in certain contexts, positive and negative infinities are very useful.

  • 10 people got shot in the knee by an arrow after watching this video

  • Hilarious!

    

  • Hilarious!

    

  • 9 People don't understand that this line has a slope of rise/run

  • ahahahah

  • I wish the education system was as effective as this.

  • XD When the cat showed up I was like......what just happened.... O_o
