Geometry x y z11/6/2022 ![]() Cartesian coordinates of three-dimensional space You can change the location of the point by dragging it with your mouse. The Cartesian coordinates $(x,y)$ of the blue point specify its location relative to the origin, which is the intersection of the $x$- and $y$-axis. It's similar to the above figure, only it allows you to change the point.Ĭartesian coordinates in the plane. The below applet illustrates the Cartesian coordinates of a point in the plane. The following figure, the point has coordinates $(-3,2)$, as the point is three units to the left and two units up from the origin. ![]() ![]() Similarly, the second number $y$ is called the $y$-coordinate (or $y$-component), as it is the signed distance from the origin in the direction along the $y$-axis, The $y$-coordinate specifies the distance above (if $y$ is positive) or below (if $y$ is negative) the $x$-axis. The $x$-coordinate specifies the distance to the right (if $x$ is positive) or to the left (if $x$ is negative) of the $y$-axis. The first number $x$ is called the $x$-coordinate (or $x$-component), as it is the signed distance from the origin in the direction along the $x$-axis. The Cartesian coordinates of a point in the plane are written as $(x,y)$. The origin is the intersection of the $x$ and $y$-axes. The Cartesian coordinates in the plane are specified in terms of the $x$ coordinates axis and the $y$-coordinate axis, as illustrated in the below figure. ![]() The Cartesian coordinates (also called rectangular coordinates) of a point are a pair of numbers (in two-dimensions) or a triplet of numbers (in three-dimensions) that specified signed distances from the coordinate axis. Cartesian coordinates allow one to specify the location of a point in the plane, or in three-dimensional space. ![]()
