第 14 课时正比例、反比例、一次函数知识点正比例函数及其图像、一次函数及其图像、反比例函数及其图像大纲要求1理解正比例函数、一次函数、反比例函数的概念；2理解正比例函数、一次函数、反比例函数的性质；3会画出它们的图像；4会用待定系数法求正比例、反比例函数、一次函数的解析式内容分析 1、一次函数（1）一次函数及其图象如果 y=kx+b（K，b 是常数，K0），那么，Y叫做 X的一次函数。特别地，如果y=kx（k 是常数，K0），那么，y 叫做 x 的正比例函数一次函数的图象是直线，画一次函数的图象，只要先描出两点，再连成直线（2）一次函数的性质当 k0 时 y 随 x 的增大而增大，当k0时，图象的两个分支分别在一、二、三象限内，在每个象限内，y 随 x 的增大而减小；当 K 2（B）m1（C）2m 1（D）m0 时，y 随 x 的增大而7如果直线y 2xm不经过第二象限，那么实数m的取值范围是8若双曲线y（m 1）x1在第二、四象限，则m的取值范围是9已知直线y34被两坐标轴截取的线段长为5，求此直线函数解析式。10已知一次函数y x2 3 的图象经过点（1，3），是方程23 10 的一个根，且Y随的增大而增大，求这个一次函数解析式。考点训练：1 y=x 的图象是一条过原点及点(-3,32)的直线2一次函数y=kx+b
