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:
Point Settings Style Menu
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.
We don't automatically graph points of discontinuity. You can add an open point manually.
Use a table to determine where your point of discontinuity is. Then graph the point on a separate expression line.

Connecting Coordinate Points
There are different ways to connect points with a line depending on the style and substance you're looking for.
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.
