![]() ![]() The formulas of coordinate geometry help in conveniently proving the various properties of lines and figures represented in the coordinate axes. The coordinates of a point are useful to perform numerous operations of finding distance, midpoint, the slope of a line, equation of a line. Ordinate: It is the y value in the point (x, y)., and is the perpendicular distance of the point from the x-axis, which is parallel to the y-axis.Abscissa: It is the x value in the point (x, y), and is the distance of this point along the x-axis, from the origin.The point represented in the fourth quadrant (x, -y) is plotted with reference to the positive x-axis and negative y-axis.Ī coordinate is an address, which helps to locate a point in space. For a two-dimensional space, the coordinates of a point are (x, y). Here let us take note of these two important terms.The point represented in the third quadrant (-x, -y) is plotted with reference to the negative x-axis and negative y-axis. ![]()
