以直线形(主要是三角形和四边形)和双曲线为背景组合的综合题,在中考题中经常出现,直线形有顶点在双曲线上,往往沟通了一次函数和反比例函数之间的联系,直线形的有关知识与一次函数、反比例函数之间的联系.就一次函数、反比例函数而言,要知道和理解它们的定义、性质,解析式的确定和直线与双曲线交点的求法,现举数例如下. The combination of linear (mainly triangular and quadrangular) and hyperbolic background combination of questions often appear in the examination questions, the linear vertex in a hyperbola, often communicate the connection between the first-order function and inverse function, the straight line For knowledge of first-order functions and inverse-proportion functions, we should know and understand their definitions, properties, analytic formulas and the intersection of straight lines and hyperbolic curves. For example below.
