Graphing and Connecting Coordinate Points

You can plot points one at a time, a few on a line, or all in a table, whichever you prefer. Get started with the video on the right, then dive deeper with the resources and challenges below.

To plot a point, enter your values as (x,y):

You can also add multiple points on a line by separating each coordinate point with a comma:

It's also possible to add points within a table:

Clicking and long-holding the color icon in the expression line will open the settings menu of the plotted point. You will be able to show/hide the point, show/hide the label, make your point draggable, adjust the opacity, thickness, font size, position and angle of the label.

Use a table to determine where your point of discontinuity is. Then graph the point on a separate expression line.

To change the point from a closed circle to an open circle, click and long-hold the color icon next to the expression. The style menu will appear.

Using a Table to Connect Coordinate Points

When creating a table in Desmos, points can be connected by clicking and long-holding the icon next to the dependent column header. Choose from two different styles. This is also a great way to graph shapes in the calculator.

Using the Polygon Function to Connect Points

You can create a polygon by creating a table containing the vertices of the polygon.
