![]() The result looks like this: Figure 4.1.3. "-" means move to the left, so you go 4 to the left. Graph the point (-4, 3) and name it point P. Here is an example of a point graphed in a four-quadrant coordinate grid. Most coordinate grids have four quadrants. Plot (3, 5) on the coordinate grid then label it point A. Review graphing points and identifying points on quadrant I of a coordinate plane. It tells where a point is located on the coordinate plane. Again, all the x-coordinates of points located on the y-axis are 0.Īn ordered pair is a list of two numbers in parenthesis, separated by a comma like this: (5,-3). Y-coordinates are plotted in reference to this axis. The y-axis is the central line that runs up-down and is labeled with a "y". All the points located on the x-axis have a y-coordinate of 0. The x-coordinate of an ordered pair is found with relation to it. The x-axis is the line running from left to right that has the numbers defined on it and is usually labeled with an "x". The origin is the place where the two lines intersect. The coordinate grid below has one quadrant, or section, to it. It usually has two or more intersecting lines which divide a plane into quadrants, and in which ordered pairs, or coordinates, are defined. Hence, it is positive.\)Ī coordinate grid is a grid in which points are graphed. In quadrant 1, both x and y coordinates are positive. ![]() In quadrant 4, the x-coordinates are positive and the y-coordinates are negative. All the quadrants are different from each other based on the position and symbol of the x and y-coordinates. These are formed by the intersection of the x and y axes and are named Quadrants I, II, III, and IV. The x and the y-axes divide the plane into four graph quadrants. For example, if someone says a point is located in quadrant II, immediately is understood that the x coordinate of the point is negative and its y-coordinate is positive. The quadrants are used to explain the position of a point on the coordinate plane. Other than this, quadrant II has negative x-coordinates and positive y-coordinates, quadrant III has both negative coordinates and quadrant IV contains the positive values of x but negative values of y. Quadrant I contains the positive values of x and y, so it is considered to be a positive quadrant. Quadrant IV is on the lower right-hand corner of the plane.Quadrant III is on the lower left-hand corner of the plane.Quadrant II is on the upper left-hand corner of the plane. ![]()
