Draw a standard graph by having a vertical line intersect a horizontal line to make a large cross. If you are using a calculator, simply use your device's graphing application.
Plot your equation or points on the graph via calculator or paper and pencil. For more complicated equations, it is recommended to use a calculator with graphing capabilities.
Find the X point on the graph. If you have plotted an equation, there should be a line running through the graph. If you have plotted points, there should simply be dots located somewhere on the graph. The x-coordinate is the horizontal line. To find X for a particular point, draw a vertical line to the x-axis. For example, if point F is directly above the x-coordinate plane value of 300, then the x-coordinate of point F equals 300.
Identify the y-coordinate point on the graph. The y-coordinate is the vertical line running through the graph plane.
Measure Y for a particular point. To do this, draw a horizontal line to the y-axis. For example, if point F is located directly to the right of the y-coordinate value of 200, then the y-coordinate of F equals 200.
Write down the coordinates of the given point. To continue with our example of point F, the coordinates should be (300, 200). The x-value is always placed first within the parentheses, and the y-value is always second.
