Using Cartesian Coordinates we mark a point on a graph by how far along and how far up it is: The point (12,5) is 12 units along, and 5 units up. Use the results in the above tutorial, and perhaps some other points, to answer the follwoing questions.ġ - For what values of x and y is the point (x,y) situated in quadrant I?Ģ - For what values of x and y is the point (x,y) situated in quadrant II?ģ - For what values of x and y is the point (x,y) situated in quadrant III?Ĥ - For what values of x and y is the point (x,y) situated in quadrant IV?ĥ - For what values of x and y is the point (x,y) on the x axis?Ħ - For what values of x and y is the point (x,y) on the y axis?įor each situation give the coordinates of the point and use the applet to check your answer.(Note: These questions have an infinite number of possible answers).ġ - point (x,y) is situated in quadrant II.Ģ - point (x,y) is situated in quadrant IV.Ĥ - point (x,y) is situated in quadrant III.ĥ - point (x,y) is situated in quadrant I.ġ - A point (x,y) such that x > 0 and y > 0 is situated in quadrant I.Ģ - A point (x,y) such that x 0 is situated in quadrant II.ģ - A point (x,y) such that x 0 and y < 0 is situated in quadrant IV.ĥ - A point (x,y) such that y = 0 is situated the x axis?Ħ - A point (x,y) such that x = 0 is situated the y axis? Cartesian coordinates can be used to pinpoint where we are on a map or graph. You can set the angles to create an interval which you would like to see the surface. This applet includes two angle options for both angle types. (2, 3), (-2, -1), (0, -2), (2, -1), (0, 0), (-2, 3), (2, 0) You have two angles in spherical coordinates and which is the positive angle starting from x axis, on xy plane and is the positive angle starting from z axis. Tutorial 1 - Quadrants in Rectangular Coordinate Systemįor each point or ordered pair, enter x and y and plot the cooresponding point.Determine the quadrant or axis where each point is located. Hover the mousse cursor on the top right of the graph to have the option of download the graph as a png file. Hover the mousse cursor over the point to read the coordinates. Plot Points in Rectangular Coordinate SystemĮnter the x coordinate and y coordinate and press "Plot Point". Below is an applet that you may use to interactively explore points in a rectangular coordinate system. x is called the x coordinate and y is called the y coordinate. Any point on the plane corresponds to an ordered pair (x,y) of real numbers x and y. The two axes divide the plane into four parts called quadrants. The horizontal axes is usually labeled the x axis and the vertical axes is usually labeled the y axis. If needed, Free graph paper is available.ĭefinition of Rectangular Coordinate SystemĪ rectanguler coordinate system, or Cartesian plane, is a set of two intersecting and perpendicular axes forming an xy plane. ![]() Through these tutorials, you will be able to explore the properties of points and quadrants in rectangular coordinate systems. Plotting Points in Rectangular Coordinate SystemĪn online graphing calculator to graph points in rectangular coordinate system.
