If the image of inverse scale function y = K / X passes through point P (- 1,2), then the image of this function lies in__ ? Why 2,4 image line? I calculate y = x - 2, hee hee~ Why does it increase

If the image of inverse scale function y = K / X passes through point P (- 1,2), then the image of this function lies in__ ? Why 2,4 image line? I calculate y = x - 2, hee hee~ Why does it increase

Because of the scale coefficient K < 0, the two branches of the image are located in the second and fourth quadrants respectively. In each quadrant, y increases with the increase of X
