So what point uniquely hasīoth an X coordinate of three and a Y coordinate of five? Well you can see where Horizontal line that I'm drawing has a Y coordinate of five. That is the origin, and so starting at the This point is actually called the origin. So one way to think about it, you could start back Now what's the Y coordinate? Another way I should say Everything on this vertical line has an X coordinate of three. So my X coordinate says,Īll right my point is going to be this far to the right. Is you'd say all right I'm gonna start right here where my axes intersect and I'm You can view it as how farĭo we move to the right along the X axis. This first coordinate, this is our X coordinate. Will interpret these points, it'll say all right,

Typically work it through, the standard way that people Specify a point on this plane? Well the way that we So how does three comma five, how do these coordinates Might call it other things, but most of the time it's In the vertical direction, this is typically known as the Y axis. In the future it mightīe called other things, and the one that goes up down One that goes left right here, this is known as the X axis, or it's typically known as the X axis. This is often known as our coordinate plane. Little bit of terminology out of the way. Where a point on the plane is? So let's first get a How can these two numbers be represented as a point on the plane, or how can these tell you What we're going to do in this video is think about how do we take two numbers and associate them with a Right, and I would end up right over there. So for example, the number two, I would go, I would start at zero, I'd go one, two to the You're probably familiar with the notion of a number line where we can take a number and associate it with a point on the number line.
