You may create new objects (e.g. points, lines, functions) by either using the [i]Graphics Tools[/i] provided in the [i]Toolbar[/i], or by entering their coordinates or equations directly into the[i] Algebra Input[/i].[br][br][img]https://wiki.geogebra.org/uploads/3/36/Algebra-Input.png[/img][br][br][u]Note:[/u] You may drag existing points in the [img]https://wiki.geogebra.org/uploads/thumb/c/c8/Menu_view_graphics.svg/16px-Menu_view_graphics.svg.png[/img] [i]Graphics View[/i], or change their coordinates in the [img]https://wiki.geogebra.org/uploads/thumb/4/40/Menu_view_algebra.svg/20px-Menu_view_algebra.svg.png[/img] [i]Algebra View[/i].

You may delete an object from the [i]Algebra View[/i] by selecting the [button_small]x[/button_small] button next to it.[br][br][img]https://wiki.geogebra.org/uploads/d/dc/AlgebraInput-PlusX.png[/img]

Create new points by using the [icon]https://www.geogebra.org/images/ggb/toolbar/mode_point.png[/icon] [i]Point [/i]tool, as well as by entering their coordinates into the [i]Algebra Input[/i]. Afterwards, change the position of the existing points.
