Given that the image of inverse scale function y = - 2K / X passes through point 2. K + 1, judge whether point G (K + 1,2) is on the function image

Given that the image of inverse scale function y = - 2K / X passes through point 2. K + 1, judge whether point G (K + 1,2) is on the function image

When k = - 1 / 2, point G is on the image, otherwise it is not
