坐标平面上任何一点与一对有序实数一一对应.一些特殊位置点的坐标有其独特的规律,熟练掌握这些特殊位置点的坐标特征,对我们解题时由坐标找点、由点确定坐标、确定点与坐标轴的位置关系有很大帮助.下面对一些特殊位置点的坐标特征进行相应解读,供同学们在学习时参考.一、各象限内点的坐标符号特征 Any point on the coordinate plane corresponds to a pair of ordered real numbers One by one, the coordinates of some special position points have their own unique rules and are familiar with the coordinate characteristics of these special position points. When we solve the problem, we find the coordinates by coordinates Determine the coordinates to determine the location of the relationship between the coordinates of the point is of great help to the following some of the special location coordinates of the corresponding interpretation of the coordinates for students to learn when reference First, the coordinates of each quadrant within the symbolic features
