把几何图形植入平面直角坐标系中,与反比例函数的图像有机地结合起来,构成代数与几何综合性较强的中考试题,这是中考试卷中一道靓丽的风景线,本文选取几例进行分析,请大家欣赏。例1如图1,Rt△ABO的顶点A是双曲线 y=k/x与直线y=-x+(k+1)在第四象限的交点,AB⊥x轴 The geometry is implanted into the Cartesian coordinate system and organically combined with the image of the inverse proportion function to form a comprehensive examination of the algebra and geometry. This is a beautiful landscape in the examination paper. This article selects a few cases for analysis, Please enjoy. Example 1 As shown in Figure 1, the vertex A of RtΔABO is the intersection of the hyperbola y = k / x and the line y = -x + (k + 1) at the fourth quadrant, and the AB⊥x axis
