A Cartesian plane consists of one x-axis and one x-axis.
A T-chart is a tool used in mathematics for making graphs on a Cartesian plan, or x-y coordinate system. A Cartesian plane is one way to visualize what the graph of an equation, or function, looks like. The tool is called a T-chart because the shape of the chart looks like the letter "T." A T-chart is a useful way to figure out and organize an equation's x-y coordinates before graphing.
Instructions
- 1
Draw a large letter T on your paper.
- 2
Write "X" above the left cross stroke of the T and then write "Y" above the right cross stroke.
-
- 3
Write your x-coordinates in the left hand column of your chart, under the cross stroke. For example, you may have x-coordinates of 1, 2, 3 and 4.
- 4
Plug your x-values into your function to get the corresponding y-values, then write those values in the right hand side of the chart. For example, if your function is y=5x, then the first y-value in this example is 5 * 1 = 5.
- 5
Draw an x-y axis on your graph paper, and then label the axes appropriately. In this example, label the x-axis from 0 to 5 and the y-axis from 0 to 20.
- 6
Plot the points from your T-chart on your x-y axis. In this example, plot (1,5), (2,10,), (3,15), (4, 20).
