# 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.

- how do you do a coordinate pair that is in the middle of 2 numbers?(5 votes)
- 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.

- Where do I find the points earned?(1 vote)
- If you watched the video for the first time all the way through, you can know that you have received 850 energy points. For every consecutive time that you watch it, you earn 100 energy points.(6 votes)

- How will i know where to put (-7/0) at on the graph(2 votes)
- 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.(3 votes)

- How do you know which number to put first in the pair??(1 vote)
- Think of it as entering a building. First you need to find the location and then you need to find the floor to go to. The first number is the one on x axis and the next is on the y axis. Hope this helped!(5 votes)

- understand the four quadrants already but where would the point ( 0,0 ) lie in? The X and Y axis?(2 votes)
- The point where the x and y axes intersect, and that would be the origin.(2 votes)

- I understand the four quadrants already but where would the point ( 0,0 ) lie in? The X and Y axis?(3 votes)
- (0,0) is the origin, so it is in the middle of the 4 quadrants.(2 votes)

- Where would 2 1/2 go on the plane?(1 vote)
- You would need to go 2 units toward the right or x direction. Then you have to go 1/2 a unit in the up or y direction.(0 votes)

- all points are 3 units away from the point (-1, 4) graph(1 vote)
- Which quadrant would the origin (0,0) be in?(1 vote)
- Directly in the middle of the graph. It wouldn't be in a quadrant.(1 vote)

- could you be normal and do what i ask(1 vote)

## 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.
