Finding the point not graphed

Some of the given ordered pairs are already graphed on the coordinate pane in this example, but not all of them. Can you tell which haven't? Created by Sal Khan.

      Let us say you get 2 and 1 half (2 1\2) and 3. The points are (2 1\2, 3) Your grid has to be in halves. In the grid, the points have to be like this: 0, 1\2, 1, 1 1\2, 2 and so on. That way, you will have space to put it in.
      But let us say you have it into fourths. 2\4 is equal to half, so 2 and 2\4 is equal to 2 and 1\2.
      Hope this helped!

    Oops! In the "About" section, below the video, may I draw your attention, it says: "Some of the given ordered pairs are already graphed on the coordinate pane <-- (THIS IS ME: this supposed to be "plane"!) in this example, but not all of them. Can you tell which haven't? Created by Sal Khan." It says "pane", it's supposed to say "plane". Oh no! Is anybody else noticing that? CAN SOMBODY FIX IT? PLEASE ANSWER...!` 

    (I know that the big lettering is unusual, but I want people to read this and figure out the mistake! Thats little disturbing but it has its purpose.)

      Think about it like this:
      You have to first get in an elevator in order to go up.
      So you first start on the horizontal line (x-axis) to get in, and then you go to the vertical line (y-axis) to go up or down.

      Example: Plot (-7,2)
      First you get in the elevator, so you go -7 to the left on the x-axis.
      Then the elevator goes up (+2) on the y-axis.
      Then you just plot the point where you end up (if the x or y coordinate is zero, then you don't move).

      Hope this analogy was somewhat helpful.

    I understand the four quadrants already but where would the point ( 0,0 ) lie in? The X and Y axis?

Video transcript

Consider the following coordinate pairs. And they give us a bunch right over here. Which of those pairs is not graphed below? So let's see, 3 comma negative 2. So 3 comma negative 2, well, actually, that looks like that first one is not graphed. So 3 comma negative 2 isn't graphed. And you can verify that all of these others do seem to be graphed. 4 comma negative 8 is right there. Negative 8 comma 3 is right over here. 4 comma 6 is right there. And negative 1 comma 0 is right there. So let's do a couple more of these. So is negative 5 comma 0 graphed? Yep. It's right over there. Negative 4 comma positive 5 should be there. So that's not graphed. So let me just select that one. Let's do one more of these. Negative 8 comma 4, so negative 8 comma 4, we got lucky. The first one is not graphed-- negative 8 comma 4. And we're done.
