The abscissa of point A is negative, the abscissa of point B is positive, and the absolute value of a negative and a positive is 2, that is to say, the sum of the distances from point A and point B to the origin is 2. In addition, ac=2bc can make use of the similar knowledge points of triangles to make a vertical line through the A-Y axis, a vertical line through the B-X axis, and then a vertical line through C to the vertical line between the B and X axes (I won't draw it, so the two triangles formed are similar, and the ratio of the vertical distance from point A to the origin of point B is 2: 1.

I just got that their sum is 2, and now I know their abscissas, and then I bring them into the inverse proportional function to get the ordinate, and then I bring these two coordinates into the function to get the result.

Answer d

Very shallow. Think about it a little.
