![]() ![]() We’ll need an expanded plane, so let’s make one that goes from -5 to 5 on both the x and the y axis. Let’s take it a step further and graph a very simple equation. It’s important to note that our first point is located on the fourth quadrant, whereas our second point is located in the second quadrant. And then continue up to 2 on the y axis, right there, and we mark our point. First we find -3 on the x axis, which is right here. Let’s try another, say you wanted to find say (-3, 2). Then, go down to -2 on the y axis, then we mark our point of (1, -2). Our first step would be to find 1 on the x axis. Say you were given the coordinates of (1, -2). To bring it all together, let’s look at some examples. As you can see, the quadrants are typically labeled using Roman numerals. The top right is the first quadrant, the top left is the second quadrant, the bottom left is the third quadrant, and the bottom right is the fourth quadrant. Each of these squares is called a quadrant. You may have noticed that the plane, with the intersection of the x axis and y axis, has four “squares.” So right here. Meaning, for any given point, we write its location on the x axis first, then it’s followed by the location of the y axis. Similarly points below the origin have a negative y value, whereas points above the origin have a positive y value.Įach point plotted on the plane has a set of coordinates, written in the following manner: (x, y). Then we move above the origin, and we do 1, 2, and 3.Īs you can see, points to the left of the origin have a negative x value, whereas the points to the right of the origin have a positive x value. We do the same thing with the y axis, starting at the very bottom, -3, -2 and -1. This may look familiar to you as it resembles the traditional number line you may have used to solve math problems. After the origin, which as we mentioned has a value of zero, we’ll continue with 1, 2, and 3. We’ll begin all the way on the leftside and label it -3, -2, and -1. The lines intersect at what is called the origin, right there, which has a value of zero. The x axis is used to designate the horizontal location of points on the plane, whereas the y axis is used to designate the vertical location of points on the plane. The horizontal line is called the x axis, and the vertical line is called the y axis. The plane consists of two perpendicular intersecting lines, one horizontal and the other vertical. Legend has it that while laying in bed, Descartes noticed a fly on the ceiling and developed his plane to indicate the fly’s position. René Descartes was a French philosopher who came up with a plane upon which numbers and equations could be graphed. How is this accomplished? That is exactly what we will explore today in this video about the Cartesian coordinate plane. Similarly, the numbers, equations, and expressions you are familiar with from your experience with algebra can also be expressed in a visual format – such as in the form of lines and other shapes. The coding is all textual in nature, meaning it consists of words, numbers, and phrases, but it results in the physical images, lines, boxes and layouts that you see on the website. These graphing worksheets will produce a polar coordinate grid for the students to use in polar coordinate graphing problems.If you have ever created a website before, you know that underneath all the images, buttons, and menus are lines and lines of computer code. These graphing worksheets will produce a single or four quadrant coordinate grid for the students to use in coordinate graphing problems. These graphing worksheets will produce a blank page of standard graph paper for various types of scales. These graphing worksheets will produce a four quadrant coordinate grid and a set of ordered pairs that when correctly plotted and connected will produce different characters.
