过双曲线y=k/x(k≠0)上任意一点引x轴、y轴的垂线,所得矩形面积为|k|.这个被称作k的几何意义的结论,反映了双曲线上点的坐标的重要特征,实际上是反比例函数y=k/x(k≠0)的重要性质,只是人们对此没有引起足够的重视和自觉地加以运用罢了.下面仅以2014年的中考试题为例,说明它在解题时的重要作用, The hyperbolic line y = k / x (k ≠ 0) at any point on the x-axis and y-axis perpendicular to the resulting rectangular area | k | This geometric significance of the so-called k conclusion, reflecting the hyperbolic Important features of the point coordinates, in fact, is an important property of the inverse function y = k / x (k ≠ 0), but people did not pay enough attention to this and consciously apply it. For example, explain its important role in problem solving,
