How to draw a line using cartesian coordinate system on graph paper?

The Cartesian coordinate system in two dimensions (also called a rectangular coordinate system) is defined by an ordered pair of perpendicular lines (axes), a single unit of length for both axes and an orientation for each axis. The lines are commonly referred to as the x- and y-axes where the x-axis is horizontal and the y-axis is vertical. The point where the axes meet is taken as the origin for both, thus turning each axis into a number line. For a given point P, a line is drawn through P perpendicular to the x-axis to meet it at X and a second line is drawn through P perpendicular to the y-axis to meet it at Y. The coordinates of P are then X and Y interpreted as numbers x and y on the corresponding number lines. The coordinates are written as an ordered pair (x,y).

How to use Cartesian Coordinates in AutoCAD

Cartesian co-ordinate system is used to represent the X and Y coordinate values. We can draw elements by using a Cartesian coordinate system in AutoCAD. Generally in Cartesian coordinate system the x and y coordinate values are separated with comma (“,”). 1. See the two-dimensional cartesian coordinate grid system in the below image. 2. Generally co-ordinate system represents with its x and y co-ordinate values enclose with brackets. The first value in the enclosed brackets is for X value and the second value in the enclosed brackets if for Y value. The below image represents the line from (2,1) to (4,5). Syn: Type "LINE" and press ENTER KEY from key board. (the data we typed is inserted in command window). Then type 2,1 and press ENTER KEY. Then again type 4,5 and press ENTER KEY. Press <Esc> (escape) key to exit from line command. 3. The bellow line is drawn from (-2,-1) to (0,0). Syn: Type "LINE" and press ENTER KEY from key board. (th...
