• Why would I need to know this in real life?
• I really have no clue
• this is not free vbucks
• What do you mean! This is off topic😩
• what does it mean when it says not graphed
• how do you use graphing in your everyday life?
• is graphing points like a bar graph?
• In a way, yes. Over the course of 2 days, you can have eaten 4 tubs of ice cream (2, 4), Over the course of 5 days, you can have eaten 8 tubs of ice cream (5, 8), etc. You can make it a bar graph if you want.
• In the video, why is 8 x and not y?
• actually this might be better than my first answer so its bacily like asking why are x and y axis on graphs so The horizontal axis is called the x-axis.And the vertical one is the y-axis.Cartesian points are written as xy pairs in parentheses, like so: (x, y). To graph a point, first locate its position on the x-axis, then find its location on the y-axis, and finally plot where these meet.The center point of the graph is called the origin and is written as the point (0, 0) because it's located at the zero point on the x-axis and the zero point on the y-axis. its kinda like that and hope this is better than my dull past answer

hope this helped :/ -GreyLeaf
• how can i remember the "y" and the ''x'' side ... its to hard for my to remember
• Try this, think of "x" as the ground that you are standing on and "y" tells you if you are going up to the sky or falling in a hole. So "x" is straight across and "y" goes up and down. Like saying "Why am I Flying?" OR "Why did I fall in the hole?". Hope this helps. So when you see something like (6,8) you start on the ground (6) and then you fly up into the sky (8).

• ok it is final I have no idea anymore can someone please help me out I had the hang of it at first but then I just lost all of it. It is now confusing me
• never mind got it this is actully pretty easy😊

## Video transcript

We are asked to plot 8 comma 10. So the first number in this ordered pair, this is our x-coordinate. This tells us how far do we move in the x direction. It's a positive 8, so we move 8 in the x direction. And then the second number in our ordered pair is 10. That is our y-coordinate. That tells us how far we move in the y direction. Since it's positive, we move up 10. So we move up 10, all the way over here. And you could have thought about it either way. You could have said, hey, look this is our y-coordinate. This is 10. So I could move up 10. And then my x-coordinate is positive 8. So I'll move 8 along the positive x-axis, or I'll move 8 to the right. You see right over here I have moved 8 to the right-- 1, 2, 3, 4, 5, 6, 7, 8. And I have moved 10 up-- 1, 2, 3, 4, 5, 6, 7, 8, 9, 10. You might be tempted to move 8 up and then 10 to the right, which would put you there. But then you would have had the two numbers mixed up. You would have had the x and the y-coordinates mixed up. The 8 tells you how far to move in the horizontal direction. The 10 tells you how far to move in the vertical direction. Let's do a couple more of these. Plot 6 comma 10. Well once again, the first number in the ordered pair is the x-coordinate, how far we move in the x direction. So we move 6 to the right. And then the second number, the 10, tells us our vertical coordinate, our y-coordinate. So it's positive 10. So we move 10 up. Let's do one more-- 5 comma 7. So my horizontal coordinate is 5, so I move 5 to the right. And then my vertical one is 7, or my y-coordinate is 7. So I move 7 up-- 1, 2, 3, 4, 5, 6, 7. And as long as you remember which one is horizontal and which one is vertical or which one is the x-coordinate and which one is the y, you should be fine. You could say, hey look, this is my y-coordinate, 7. So I'm going to move 7 up. And my x-coordinate is 5, so I'm going to move 5 to the right. And it will get you to that exact same point. This specifies exactly one point in the coordinate plane.
