The steps for plotting a point are summarized below. If you look over to the y-axis, you should be lined up with − 2 on that axis.ĭraw a point at this location and label the point (−4, −2). Now move 2 units in a negative direction (down). The y-coordinate is − 2 because it comes second in the ordered pair. Start at the origin and move 4 units in a negative direction (left) along the x-axis. The x-coordinate is − 4 because it comes first in the ordered pair. With an x-coordinate of 4 and a y-coordinate of 3, you have the ordered pair (4, 3). This number is the y-coordinate, the second number in the ordered pair. The 3 indicates that, after leaving the x-axis, you traveled 3 units up in the vertical direction, the direction of the y-axis. This is the x-coordinate, the first number in the ordered pair.įrom 4 on the x-axis move up to the point and notice the number with which it aligns on the y-axis. The 4 indicates that, from the origin, you have traveled four units to the right along the x-axis. To identify the location of this point, start at the origin (0, 0) and move right along the x-axis until you are under the point. Since the origin has an x-coordinate of 0 and a y-coordinate of 0, its ordered pair is written (0, 0). Note that the x-coordinate is listed before the y-coordinate. In an ordered pair, such as ( x, y), the first value is called the x-coordinate and the second value is the y-coordinate. An ordered pair tells you the location of a point by relating the point’s location along the x-axis (the first value of the ordered pair) and along the y-axis (the second value of the ordered pair). Locations on the coordinate plane are described as ordered pairs. Quadrants are named using the Roman numerals I, II, III, and IV beginning with the top right quadrant and moving counter clockwise. These four sections are called quadrants. The intersecting x- and y-axes divide the coordinate plane into four sections. The origin is at 0 on the x-axis and 0 on the y-axis. The point at which the two axes intersect is called the origin. The horizontal axis in the coordinate plane is called the x-axis. It consists of a horizontal axis and a vertical axis, number lines that intersect at right angles. The coordinate plane has similar elements to the grid shown above. You’ll find a blue disc is at this location on the map. For example, you can find the item that exists at square “4F” by moving your finger along the horizontal to letter F and then straight down so you are in line with the 4. The general location of any item on this map can be found by using the letter and number of its grid square. Notice that the letters A-F are listed along the top, and the numbers 1-6 are listed along the left edge. This “map” uses a horizontal and vertical grid to convey information about an object’s location. For example, have you ever used a gridded overlay to map the position of an object? (This is often done with road maps, too.) Visit for Coordinate Graph Printables.You have likely used a coordinate plane before. Then, ask them to check their work by toggling the coordinates back on. Challenge students to graph a set of coordinates with the coordinates display toggled off. Then, walk them through how to use the x and y axes to show coordinates or make line segments. Teach coordinate graphing easily by displaying this tool for your class. Clear the graph using the trash can symbol. Toggle coordinates on or off with the button above the trashcan. Choose the units of your graph on the x and y axes by clicking the numbers on the right side of the graph. Use different colors for your segments by selecting the colors to the top right of the graph. Or, click and drag to make line segments. To use the online coordinate graph tool, simply click on the intersection of lines to make a point. This interactive online coordinate graph tool allows students to practice graphing coordinates.
