![]() When plotting points on a coordinate plane, remember to move right, along the “x” access, and then move up along the “y” access. This is the spot on the coordinate plane that matches the numbers in our point. Start where you left off on the “x” axis, and move 3 spaces up, along the “y” axis. The second number in the point represents how far along the “y” axis to move. Now, move to the right along the “x” axis, a total of 5 spaces. Remember, the first number listed tells how far along the “x” axis the point is located. For this example, let’s plot the point five, three. Let’s plot a point on the coordinate plane. When plotting points on a coordinate plane, always begin at the origin. It lets us know how far along the “y” axis the point is located. The second number in the point, is called the “y” variable. We refer to the first number as the “x” variable, because it lets us know how far along the “x” axis the point is located. You will need to use both the horizontal axis and the vertical axis in order to plot points on the coordinate plane.Īny point on a coordinate plane can be represented by two numbers. A coordinate plane has a horizontal axis, which is often referred to as the “x” axis, and a vertical axis, known as the “y” axis.

Previous Lesson Table of Contents Next Lesson Which quadrant contains only negative coordinates?.(a) If a point lies on the x-axis, what is its y-coordinate? (b) If a point lies on the y-axis, what is its x-coordinate?.The horizontal x-axis and the vertical y-axis divide the plane into four quadrants which are numbered counterclockwise from the top right. The location of a point is called its coordinate. Objectives have been introduced to the Cartesian coordinate plane understand the four quadrants of the Cartesian coordinate plane be able to plot points on. Negative x is to the left and negative y is down. ![]() Many maps, such as the Campus Map shown below, use a grid system to identify locations. Positive x is to the right and positive y is up. Graph points (ordered pairs) on a coordinate plane. Any point can be described as the distance it is from the origin along the x-axis and along the y-axis and is written as ( x, y). The point where the axes cross is called the origin. The Cartesian, or rectangular, coordinate system consists of a horizontal x-axis and a vertical y-axis. ![]() It is sometimes called the rectangular coordinate system because the grid is made of squares. René Descartes first published the coordinate system that bears his name in 1637. These two numbers are the coordinates of the fly's position. If one corner of the room was taken as a reference point or origin, the fly's position could be described as the number of tiles horizontally from the origin followed by the number of tiles vertically from the origin. He wondered how he could describe the fly's position on the ceiling. As he was staring up at the ceiling, he saw a fly. ![]() There is a legend that claims the Cartesian coordinate system was discovered when René Descartes was sick in bed.
