On the image of inverse scale function y = K / x, any point is perpendicular to two coordinate axes. The area enclosed by two perpendicular lines and coordinate axes is_ This point and a perpendicular foot and coordinates What is the area of the triangle formed by the origin————

On the image of inverse scale function y = K / x, any point is perpendicular to two coordinate axes. The area enclosed by two perpendicular lines and coordinate axes is_ This point and a perpendicular foot and coordinates What is the area of the triangle formed by the origin————

The area enclosed by two vertical lines and coordinate axis is | K |;
The area of the triangle formed by this point, a perpendicular foot and the origin of the coordinate is | K | / 2
