在学习一次函数的图象及其性质时,经常会遇到一次函数y=kx+b的图象与系数的关系问题,这类问题比较综合、灵活,很多同学考虑不全面,失分率比较高,甚至有的同学无从下手,特别是初学者尤为明显.下面就以三种类型为例来说明这类问题的解答对策. In learning a function of the image and its nature, often encounter a function y = kx + b image and the relationship between the coefficient of such problems more comprehensive and flexible, many students consider not comprehensive, the fractional rate comparison High, and even some students can not start, especially for beginners is particularly obvious. Here are three types as an example to illustrate the solutions to such problems.
